Water for fish in the aquarium


Choosing water for the aquarium

There is no absolutely pure water in the world, it is mined in laboratories using step-by-step distillation. Water from a water supply system or natural source always contains impurities of various substances that play an important role in the ecosystem. Considering that many modern people keep fish at home, everyone wants to use the highest quality water for them. But what should be the water so that it can fill the home aquarium?

What you need to know about spring water

For a long time it was believed that spring water, recruited from a crystal clear stream, is best suited for ornamental freshwater fish. Perfectly clean, transparent, odorless and dirt free - that's exactly the kind of tank you can fill! It turned out that typing this is not always safe. Its difference from tap water is high rigidity. Even the soap in it is difficult to dissolve, what can we say about fish food. Due to the high content of magnesium and calcium salts, it has a detrimental effect on the health of the fish and their offspring (eggs). Unfortunately, the water from the spring is not recommended to add to an artificial aquarium. Occasionally it is mixed with water to increase rigidity.

Distilled and rainwater

Since the springs have increased hardness, can it be better to pour soft water into the tank - rainwater or distilled water? Again, not always - just mixing it with the plumbing. There are fish that love the environment with softened water, but many freshwater species still prefer medium, neutral water. Such water flows in domestic rivers and lakes - you can pour it purified into the aquarium, filling it with not all the space.

What habitat most love aquarium fish

What water is needed for an aquarium? Combining water from different sources, it is impossible to achieve the ideal parameters. How many fish, so many requests. Some fish can live in the melt water of mountain lakes, others - in the brown marsh. In the first case, the water is very hard, in the second - soft. Fish have to settle in a different environment. It turns out that some fish are orderlies who love rotten water, others do not tolerate such parameters. Rotten environment is detrimental due to humic acids. Many freshwater biotopes of our country have pH neutral water, medium acidity, low alkalinity. For most aquarium fish, it is suitable.

Aquarium water for unpretentious fish

Water that must be prepared for not very capricious ornamental fish requires preliminary preparation. In the general aquarium it is necessary to fill in soft (sometimes medium hard) pH-neutral water. This can be plain tap water. In it, live-off and viviparous fish, which perfectly adapt to different conditions, take root well.

See how to change the water and care for the aquarium.

The degree of hardness can be measured using litmus paper, the temperature of the water - with a thermometer. Water of high degree of hardness is recommended to be mixed with soft rainwater (filtered) or distilled. Also, water from clean, melting snow or ice. The listed types of water can be collected in a clean container only after prolonged precipitation; it is enough to pour 30% soft water into infused water from the tap.

Water from the tap can not be poured immediately. It is better to pour it into a glass, and see if the glass is covered with bubbles, whether a strong smell will emanate. Such water is saturated with compounds of gases that fell into it during filtration at the treatment plant. Having let the fish in such a liquid, the pet's body will instantly become covered with bubbles, which will penetrate into the gills and internal organs. As a result, the fish will die. In addition to gas, chlorine is added to water for disinfection, it will also poison living beings.

To get rid of gases, tap water can be poured into glass containers, and let it settle there for several days (2-3 days). There is another quick way: pour water into enameled ware, bring it to the stove to 60 or 80 degrees, set aside and cool. Boiled water is harmful - it leaves on the walls of dishes scale calcium carbonate and magnesium. Boiled water can be poured into spawning, but in extreme cases. To fill the entire area of ​​the aquarium with boiled water will take a long time. Another nuance - boiled water kills all the useful microflora.

If you do not have water supply (this occurs in our time), you should go to a clean river or lake (where there are no signs "No swimming is prohibited!", Etc.), and take water from there. If it is clean, river fishes (perch, bream, roach) really live and flourish in it, there is a water grid plant, which is a good sign. To destroy parasites, such water is heated in an enamel pot to 80-90 degrees, but not to make boiled water out of it. The parameters it will be different from the liquid from the tap, so think about whether to take such a risk. You can go to another house, and get running water there.

In addition to thawed, spring, rain and distilled water, it is advisable to pour 30% of the water from the old aquarium to the infused liquid from the tap. If he was kept safely, the fish and plants did not hurt there, the water in him was not muddy - this is a find. In the old (residential) aquarium water, whether it has been poured from a tap for a long time, there are many useful microbacteria that will create in the new dwelling the natural biological environment. In a residential aquarium environment contains a number of organic impurities that are very useful for the aquatic environment. They make the water more acidic, do not allow the putrefactive and pathogenic bacteria to multiply. If high-quality and proven water is poured into the tank, all its inhabitants can be healthy.

10 commandments novice aquarist

What to do to breed fish? Where to begin? How to make the first launch of the aquarium at home? What are the most unpretentious fish? Do I need seashells in the aquarium? What kind of ground to choose? These and many other questions arise for beginning aquarists when they decide to buy a home aquarium and breed fish. Of course, experienced aquarists already know many secrets and nuances in this difficult hobby of fish. And what should newcomers do in this case? And in today's article we will dwell in detail not only on what aquarium for beginners is, but also on what to do in order to create a real work of art at home.

Rule one - the fish can not overfeed!

After acquiring a new artificial pond for the house, keeping the fish is better to start with its feeding no more than once a day. Of course, then you can feed it more often, but little by little. After all, an aquarium is, first of all, a closed habitat. If there is a lot of food, it is not eaten by fish, then it gets into the ground and begins to rot. From overfeeding the fish start to hurt, and then they completely die. How do you know if the fish are overfed or not? It's simple. Food, after getting into the aquarium should be eaten immediately, and not sink to the bottom. True, there are such fish as catfish. It is they who eat the food that fell to the bottom. Also, the fish need to arrange fasting days, but only once a week.

Rule two - care for aquarium

Aquaria - a very delicate matter. If you buy aquariums for beginners, it is best to focus on their equipment and only then think about starting. After all, everything requires maintenance and care, and the aquarium is no exception to the rules. In the new aquarium, the water needs to be changed not immediately, but only after several months. And the basic rules for the care of an artificial reservoir - is the replacement of water, but partial. You also need to look for algae. Do not forget to change the filter, clean the soil. Do not forget to also check the readings of the thermometer. And remember, you need to disturb the aquatic inhabitants as little as possible. Fish do not like it.

The third rule - conditions for fish: what should they be?

In order for the inhabitants of their future home to always be in order, it is necessary to properly maintain them. First of all, they need to create optimal conditions for their habitat. And for this, before purchasing fish in the pet store, carefully read the information about a particular species of fish. After all, one fish may simply not fit the environment, or the decor, which equipped the vessel.

The fourth condition is the right equipment.

Remember the main rule. First you need:

  1. Aquarium and minimal equipment for it.
  2. Priming.
  3. Plants.

And only after the acquisition of all of the above, you can think about choosing the fish. Artificial pond need to choose not very small. What is necessary from the equipment? So it refers to:

  • filter;
  • thermometer;
  • heater with thermostat;
  • lighting.

And when all this is acquired, you can do the installation of the vessel in your room. It is best to do this on a flat surface, before laying the tourist mat under the bottom of the aquarium. You also need to wash the soil and sand, pour it into the aquarium and fill it with cold tap water. Install a filter and heater (especially important to monitor the temperature of the water in the winter). Because from the cold fish can die.

Next, heat the water to 20 degrees and begin to plant the plants. Planting a home aquarium should be live plants. They are simply necessary. Even if there are fish in the aquarium that like to feed on plants, it is better to simply feed them more. Water will be muddy at first. And it is here that you should not hurry too much. It is best to wait about 7 days. And already after the water becomes clear, you can launch fish.

Important! Buying fish, do not forget to clarify whether they will get along together.

The fifth rule - the filter must be washed in the aquarium water

Do not make a fatal mistake. The filter should not be washed under running water, and aquarium. This is necessary in order to preserve the balance that is inside the filter.

The sixth rule - to collect more information about the fish

Do you want to avoid problems that may arise after the launch of the fish in the aquarium? Do not hesitate, ask the seller in the pet store about the fish and their contents, read different information and then everything will be right. After all, all the fish are different. Some are small, others are big. Some calm, others aggressive. And there is, for example, and predatory. Remember that it is on your right choice that both the comfort of the fish and the internal balance in the vessel's ecosystem depend.

What kind of fish can you choose? The most classic is guppies. Their content does not cause difficulties. So, they are unpretentious, viviparous and eat different food. It is very easy to distinguish the female from the male. Swordtails are also viviparous, so there will be no problems with the fry. Swordtails are similar to guppies in behavior and content. Danio rerio are very popular in aquariums. They are elegant, unpretentious and very mobile. Eat all kinds of feed. Another type of fish - the cardinal. They are very small and unpretentious. They need to be properly maintained, and then they can live up to 3 years. When choosing fish, pay attention to their color and color. They should not be pale.

Important! Novice aquarists - do not breed many fish at once!

The seventh rule - the launch of a new fish spend slowly!

As mentioned above, the launch of the fish should be done only when the artificial reservoir is settled at home. Remember that if all the rules are not followed, the water in the aquarium will quickly become cloudy and the fish will die.

Quite often, a situation arises when, after acquiring a fish, many beginners do not know what to do next ... For experienced aquarists, this is not a problem, since their launch of the fish takes place on the machine. But beginners may have problems. First you need to put the bag with the fish just in the aquarium. Let it float there. Thus, the fish gets used to the new environment. And the fish that are already in the aquarium in this way will get to know it. Then you need to start lowering the package below, so that the water from the aquarium is filled in the package. Let it still be a little time, and then launch the fish into the aquarium from the package.

Important! The more expensive a fish is, the more bother it is!

Eighth rule - water quality

Whatever fish was purchased, any of them is very sensitive to the chemical composition of water. And filling the aquarium should start with checking the composition of the water. All water composition parameters can be checked using special tests for aquarium water. For this you need to purchase such a test.

Then collect the required amount of water in a clean, well-dried test tube, glass, glass. Add a reagent indicator to the water, shake the tube with water. After 5 minutes, compare the result in the reference card. According to the results you need to take action. If the water was very hard, then it should be softened.

The ninth rule is a good seller.

Now during the computer technology for any question, you can find any answer at home by going to the network. But live chat is better. And if luck and fate will bring with an avid aquarist, then the success of the novice is almost guaranteed to breed fish at home. It would also be nice to make friends with the seller at the pet store, thus obtaining not only an experienced adviser, but also in the future, a reasonable discount and the right to make the first choice of the item you like.

The tenth rule - aquarism is my hobby!

The most important thing in aquarism is to fish with great enthusiasm, but without forcing yourself. Make it so that it brings pleasure and enjoyment. After all, this is a real vacation at home. Near the artificial reservoir can spend a lot of time watching the behavior of fish.

In addition, scientists have proven that running and monitoring fish leads to normal blood pressure and calms the nervous system. And if there are small children at home, then this is also a very good educational moment. After all, since childhood, caring for fish will teach them to care and attention. After all, probably, few people would like to see the first experience with the aquarium turn out to be bitter and end with the death of the fish. After all, it often happens that novice aquarists, who have not coped with the problems, put an end to their dream.

Do not leave immediately, and after a while there will come a period when an experienced aquarist grows from an inexperienced beginner who will help the same beginners, like him, who buy aquariums for beginners himself just a few weeks or months ago. Believe it is not difficult!

How to prepare the water for the aquarium - a full description.

Why do you need to defend the water?

The main reason for this is harmful impurities that can harm the inhabitants of our aquarium. After settling, solids sometimes appear in the sediment. Initially clear water after a while can grow turbid.

Many aquarists leave the water for substitution to breathe for a few days, and so that all harmful suspensions evaporate for a week. This assumption is partly true, but it cannot guarantee the quality of the prepared water.

Before we do something, we always know why we need to do it. By keeping tap water outside the pipeline, we are trying to improve its performance so that it does not harm our fish. In other words, when defending water, we get rid of most of the malicious components.

Conditionally harmful substances in the water can be divided into:

  • solid (precipitates to the bottom);
  • gaseous (volatilized from water to the environment);
  • liquid (initially dissolved and remaining in water).

The process of settling can affect only solid and gaseous mixtures, and it does not affect liquid substances in any way.

What should be the temperature of the water in the aquarium?

Water temperature for the aquarium plays a crucial role. It depends on the health and ability of fish to breed. For each species of fish, a completely different water temperature is suitable. Conventionally, all the inhabitants of the aquarium can be divided into heat-loving and cold-loving.

By heat-loving include fish living in the water, the temperature of which is not below 18 degrees. Cold fishes are individuals that easily adapt to low temperatures. They can safely live in the aquarium, the temperature in which, will not exceed 14 degrees. The maintenance of cold-loving fish is possible only in large and spacious aquariums.

It is noteworthy that if the heat-loving fish are planted in cold water, then they practically stop swimming. This suggests that significant damage has been done to their health. Preparing water for the aquarium, you should use the tips for beginners, which can be found in the special literature. So, it is possible to choose the optimum temperature for water only after it becomes known exactly which species of fish will live in it.

The thing is that in the literature for each type of fish is given the permissible threshold of the highest and lowest temperatures at which the fish will feel comfortable. В соответствии с этими параметрами можно подобрать будущих обитателей аквариума таким образом, чтобы все они чувствовали себя комфортно в одинаковых температурных условиях. Это позволит избежать огромного количества проблем, связанных с содержанием и уходом за рыбками.

How much to defend the water for the aquarium?

To finally get rid of all the harmful substances contained in the water, it must be defended for 1-2 weeks. For the backlog of water is better to use a large bucket or basin.Also, when buying a new aquarium, leave water in it and drain it at least once. At the same time, this way you can check if the aquarium is leaking. Some pet stores sell special products that neutralize chemical compounds in water. But experts recommend not to neglect the settling of water, even using these drugs.

Is there a need for water settling?

In order for the tap water to be normalized for replacement in an aquarium, it is necessary to remove from it all the harmful components - solid, gaseous and liquid.

Today, upholding is very rarely relevant. Solid components in the water supply system have isolated cases, chlorine water derivatives must be removed by air conditioning (chlorine gas is also removed), and liquid ones - only by special air conditioning. Polluted water settles for several hours, and with strong aeration much faster.

From all of the above, it is clear that it is best to use special additives for water. Settling water does not completely remove harmful substances, and in some cases it may even be harmful (a dusty film appears, stuffiness, etc.).

From personal experience:

  • I collect the necessary amount of water for the substitution;
  • add air conditioning according to the instructions;
  • perform aeration for 15 minutes;
  • I bring the temperature of fresh water (with air conditioning) into accord with the aquarium one;
  • I fill, and that's it.

The advantages of this method of water preparation: all harmful substances are removed, no need to wait until the water settles, the pots do not harm the interior of the room.

How to prepare the water?

Freshly tap water is not suitable for animal settlement. Reptiles, fish, amphibians and snails can adapt to it, but on condition that it infuses for several days.

Fresh, domestic water from the tap will destroy animals, because chlorine compounds are toxic to the sensitive organism of small creatures. On certain days, tap water contains different amounts of volatile substances, experts recommend turning on a shower and checking the steam and the presence of chlorine to check. If the smell is harsh, water should not be collected on this day.

Regardless of the season, weather and air temperature, domestic water will be different. Be observant if you want to settle the animals in clean water from impurities. Infused tap water is recommended for many pets and plants, it has an acceptable level of acidity: pH 7.0.

It forms an active reaction, creating an alkaline and acidic aqueous medium. The reaction is determined using litmus paper, which is sold in pet stores. Infusing water should not be in plastic containers; it is better to use glass jars with the lid open. The main thing is that in the prepared water, while it insists, do not get dust and insects.

You can use baking soda to raise the pH to the required level. Peat is recommended to lower the pH. Sometimes before the launch of a new aquarium in the water put samples of trees, reducing the acidity of water. The aquarium can be filled not only with tap water, but also distilled water, which is sold in pharmacies or in auto shops.

It is filled with small aquariums, but with an experienced razvodchiki warned that such water is poor in the mineral components necessary for animals. Rarely use a liquid from another aquarium, in which there is a stable biological equilibrium for normal life.

How to prepare water with permissible hardness?

Reduce stiffness by filtering and infusing. Sometimes, infused water (time - 2 days) from the tap add distilled, thawed or rain water. Plants such as roach and elodiea, reduce stiffness. There is another way - freezing. The collected water is frozen, and then thawed, defended and poured into the tank.

Increases the rigidity of the aquarium water by adding brine, pieces of chalk or limestone, coral chips to it. Coral crumb is recommended to boil (2 hours) to soften and prevent parasites. Only after all the procedures it is lowered into the tank.

It is better to run the fish in a day or two, until the water has acquired the necessary parameters. The temperature of the water in which the purchased fish, animals and plants lived should be identical to the aquarium. Again, use a thermometer, litmus paper to test. Do not neglect the recommendations that the life of pets was healthy and safe, because when kept in poor-quality aquatic environment, they may suffer.

What does water temperature affect?

Aquarium water that has a certain temperature can stimulate spawning. This applies to elevated water temperatures. However, this is not always useful for fish. So, the fish that spawn, you should not constantly keep in such conditions. Otherwise, to get offspring from them in the future will be simply impossible. Thus, when harvesting water for an aquarium, it is better to ensure that it is one degree below the norm.

Gaseous constituents of water

This type of substance evaporates through the surface of the water. Here one can consider the quantitative and qualitative compositions of dissolved gases in water. Gaseous substances in natural water enter into chemical reactions with other dissolved elements, due to diffusion they constantly circulate through the water mirror and are harmless and harmless to fish.

The method of water disinfection for your area can be found in the local water utility, this information will not be superfluous. At new water treatment plants, ozone and ultraviolet cleaning is applied, and such water can be added without fear (it is pointless to defend against oxygen and photons).

The outdated chlorine cleaning method is gradually becoming a thing of the past, but is still in use. Chlorine and its derivatives are poisons. They allow the destruction of both harmful bacteria and beneficial ones, as well as depending on the concentration of large animals and even humans.

Method of elimination of gaseous chlorine from water

Unpleasant smell of chlorine coming from freshly poured water, everyone knows. Water, being in a cup, ceases to smell after a while, and this means that chlorine molecules have evaporated.

If the fish are placed in newly recruited chlorinated water, they will die from body burns and gill petals.

Having made some observations on settling, it can be seen that chlorine evaporates quite quickly. It is not necessary to stand for water from the tap for more than a day, since the residual chlorine cannot affect the health of the fish.

The important point is the choice of dishes. The greater the area of ​​contact of water with the environment, the faster the gas exchange occurs, and chlorine disappears. From this it follows that when settling water in a large-diameter basin, it will become suitable for an aquarium much faster than using a plastic bottle.

It is impossible to cover the used dishes with a lid and even more so to twist the bottle, since there will be no place for volatilization of gas impurities, and the water which was chlorinated will remain so.

Ozone and its effect on fish

With ozone, things are somewhat different. It does not have a pronounced smell, although it carries freshness. Under natural conditions, we feel it during a thunderstorm, during the operation of air conditioners (ozonizing) and laser printers. Before water is supplied to the drinking pipeline, the process of its ozonization takes place, the ozone molecules are unstable and quickly pass into a stable compound - oxygen. Well, oxygen is not dangerous to fish.

What is pH and hardness?

pH is a pH indicator of the acidic environment. A pH of 7 is considered neutral because it is more favorable for most aquarium dwellers. In the case when it is less than 7, the water is alkaline. In order to easily determine the pH of water, it is necessary to purchase litmus papers with a color table, or specialized aquarium tests.

The second parameter of water is hardness. It is divided into temporary and permanent. Water hardness may also affect aquarium inhabitants.
In order to avoid unpleasant consequences, aquarium water should also be checked for permanent and temporary rigidity. It is measured in degrees and is calculated by adding the temporal and constant rigidity.

In the case when spawning of a certain type of fish is necessary, for example, such as neons, in which caviar can survive only in very soft water, water with low hardness content is used. However, for most avkarium fish species, water with a hardness content of less than 5 is not suitable for life and breeding. At the same time, too high water hardness, such as 25 degrees and above, is also destructive for most aquarium species. Of course, there are exceptions.

The norm, it is considered to be hardness from 5 to 25 degrees, which is favorable for the vast majority of different types of aquarium fish.

Aquarists who do not want to bother themselves with various dimensions can simply pick up certain types of fish that feel great in ordinary tap water.





Running aquarium with fish

Launching a new aquarium is a complex process that requires careful preparation. In order to properly organize the launch of a new aquarium for fish, you need to prepare the aquarium itself, plants for it, decorations, a filtration system, a backlight, and a compressor with a spray. After purchasing all the equipment, it is installed, then water is poured. But that is not all. In the aquarium should be formed favorable biological environment of beneficial bacteria.

First preparations

Choose the size of the aquarium depending on what types of plants and fish you are preparing to launch. For large fish, it is better to prepare a spacious tank of 300-500 liters or more, for a flock of small fish - up to 250 liters. For one fish, a capacity of 50-60 liters is enough, but in the way of life, not all fish are lonely, so consider this feature. In a close aquarium, it is difficult to maintain a biological balance, and if you plan to buy new fish, its volume will not be enough.

See how to choose an aquarium.

Before starting a new aquarium, you need to wash it properly. Do not use soap or other detergents. Baking soda is not toxic; it washes away all germs and alkali. Rinse the tank walls with running water 4 times. Frame aquariums can be left under water for several days, during which time toxic substances will be washed off. The water in which he was located must be drained. Check if the walls of the aquarium are leaking.

Put a clean tank in a specially prepared place. You can not put it on the window sill, in places of draft and direct sunlight. Bright lighting will trigger algae reproduction and water bloom. The place for the aquarium should be permanent. Try to put it where there will be less noise, evaporation from the room battery.

Choose a table or cabinet for an aquarium of such height and surface area that could support the weight of the structure. The surface must be smooth and clean. The water pressure at the bottom of the tank is high and the bottom may crack on an uneven surface. You can use a rubber mat as a lining.

Water and scenery in an aquarium

Now you need to prepare equipment for the aquarium. Determine where it is better to put the compressor with air ducts, how to connect the lighting and the water heater. Consider where you can leave the net for transportation, the siphon with the hose, the scraper and the water collection tank. If you have thought about where you will install the equipment, you can lay the soil substrate.

Decide in advance on the type of soil - it can be gravel, pebbles or sand. Soil needs to be processed, wash out all suspended particles and remnants of large fragments. Some types of soil need to be treated with boiling water, in any case detergent. After preparing the ground, the next day you can plant unpretentious aquarium plants in it, such as valisneria, anubias, hornolistnik, elodeya and others.

Watch the video with recommendations for choosing aquarium soil.

Next you need to pour prepared water into the tank. You can not pour the water recruited from the tap, it is harmful and toxic. Let her stand for 3-4 days to get chlorine fumes out of it. It will heat to room temperature. Take measurements of water parameters using indicators. When all indicators meet the standards, you can pour water.

Later, place stones, rocks, caves, earthenware pots and treated wood snags in the tank. Attach the filtration system (external or internal filter), aerator, heating system, thermometer. If the equipment manual allows, you can install mechanisms after the water inlet. For a decorative aquascape, all parts must be as hidden as possible. With the help of large stones, driftwood and bushes of plants you can cover the installation.

After all the preparations, the water can be poured in little by little, so that the soil does not become washed out and the water does not become cloudy. On a layer of soil you can put a ceramic plate, and pour water directly on it. Then turn on all devices and check their performance. Inspect the tank for damage.

Running fish

To properly prepare the aquarium to run the fish, you need to wait a few days, when it will establish biological balance. After 2 days in the new aquarium, the water becomes turbid - this means that ciliates and useful bacteria actively proliferate in it. This is a signal that the preparation of the aquarium was successful. After 2-3 days the water will be clean, it may turn yellow. If you add water from the old aquarium to the reservoir, the beneficial microorganisms will quickly establish biological balance. You can buy a special leaven with good bacteria in the pet store, and add it in the required proportions to the water.

After 7-8 days after adding water to the aquarium, you can run the first hardy and undemanding fish. It is correct to start schooling fish at once on 5-6 individuals and more, singles or paired fish - only in pairs. Viviparous species of fish and barbs will help the aquatic environment to quickly come into balance.

To prepare the fish for launching into the tank, they need to be placed in a portable water bag from their previous aquarium. Gradually lower the fish in the bag into the new water so that they get used to its temperature. After 20-30 minutes, the new water will become familiar to them. To avoid stress, anti-stress drugs such as Tetra Easybalance or Ptero Aqua Antistress can be added to the tank.

The optimal temperature for fish in an aquarium and how to maintain it

Fish are cold-blooded animals, the full activity of which is ensured by the constancy of the water temperature in the habitat. The body temperature of the fish exceeds the water temperature by about 1o. Changing the temperature of the habitat directly affects the health of cold-blooded organisms.

All holders of aquarium fish should understand that the life of their pets directly depends on the temperature conditions in the aquarium. What should be the optimal water temperature for different ornamental fish, and how many degrees should be reflected on the scale of the thermometer so that each fish feels healthy?

About temperature limits for warm and cold-water inhabitants of reservoirs

Tropical and subtropical regions are not characterized by frequent changes in water and air parameters. In Southeast Asia, the temperature range of air is the same throughout the year, sometimes ranges from 3 ° C (26-29 degrees), and the difference in water is almost imperceptible. In South America, hot and humid, throughout the year to air 25-28 degrees.

There are species of fish that prefer wide temperature ranges, and there are those who live only in a narrow range. Only the fry of most fish are resistant to the drop to. When the amount of dissolved oxygen in the water decreases, all fish are less sensitive to temperature changes. Hydrobionts get used to high temperatures in a few days, and to cold temperatures - in almost a month. For normal acclimatization, a gradual increase in to 1-2 degrees, and a decrease in 0.5-1 degrees is necessary.

Watch the video about the aquarium heater.

All fish species have their own upper and lower threshold to. Fish are sensitive to those parameters that go beyond the permissible limits. When the border is violated by several degrees, the health of the fish deteriorates dramatically. Frequent and sudden changes in temperature adversely affect the health of pets. In order to maintain an optimal temperature regime in an aquarium, you need to familiarize yourself with the allowable temperature conditions for warm-water and cold-water fish.

For warm-water fish to water below 18-20 degrees is considered unacceptable. In aquarium fish in this category it is possible to survive in the lower ranges for a long time. But this fish needs a lot of oxygen and space, good aeration is necessary.

For cold-water fish suitable aquarium without heating, 14-25 degrees for them - the maximum. They also need an abundance of dissolved oxygen.

Average temperature range

The fluctuation of aquarium temperatures is possible, it is even permissible within certain limits. Медленное изменение на 2-4 градуса не приведет к трагическим последствиям. Если аквариум поставлен на подоконнике или возле окна, то в зависимости от времени года в нем будет меняться температурный режим.Aquariums should not be installed near batteries and other heating systems, even heat-loving fish will not survive strong heating.

What can be the water temperature for different fish? You can set the average range of oscillation for cold-water and warm-water fish, but these are not settled in one aquarium - this is prohibited. How many degrees should be acceptable temperature limit, which would be acceptable to all:

  • 24-26 degrees Celsius

See how in the heat to lower the temperature in the aquarium.

Temperature fluctuations should not exceed three degrees! Before settling in the fish aquarium, find out what the average temperature range of their content.

It is also worth controlling to above water - this is important for labyrinth fish that breathe portions of air from the surface. As an example, you can explore the content of the labyrinth fish gourami, which, breathing the air 5o below the water, can suffocate and die. Just for them, the cold air is critical.

It is recommended to install a thermometer and thermostat for water and air to keep the gourams. Water should evaporate in a minimum amount, and to water above water should be similar to that in a pond. If gourami inhale too hot or cold air, the untreated oxygen enters the labyrinth channel, clogs it, and the fish suffocates.

Gourami are temperature sensitive because it affects the breeding cycle. Warm water is an incentive to spawn, in this period it is appropriate. If it is warm all the time, in the body of gourami the processes of vital activity slow down, the protective functions of the body are reduced. At an incorrect temperature, sex cells are not produced, and gourami will not give offspring. Surviving fry in the wrong aquarium water conditions die.

Allowable temperature for gourami in water: 23-26o, to air on the surface - 26-28o.

Is it true that cichlids tolerate different temperature ranges?

For cichlids, the content in warm water is necessary, since such a temperature of water produces the release of enzymes for saturated body color and stimulates them to spawn. Cichlids have high tolerability of both high and low temperatures, but not more than 6 hours. The tank can maintain an average temperature range. At elevated temperatures of cichlids, their color is quickly saturated, but they are depleted and live less.

At lower temperatures, the color of the cichlid tarnishes, the fry grow and develop slowly. The allowable temperature for cichlids is 24-30 degrees. The limit is 24-27 degrees. For Tanganyik cichlids, the water should not be warmer than 29 degrees. In the treatment of certain diseases of cichlids, to increase for some time.

Cichlids are indeed one of the most enduring fish in an aquarium; for a novice aquarist, many members of this family will be excellent pets. However, all types of fish require attentive care, which should not be forgotten.

Pud salt in the aquarium - how much salt to add to the aquarium?

POD SALT IN THE AQUARIUM how much salt to add to the aquarium something?

Ordinary kitchen salt is used in the aquarium world mainly for the treatment of sick fish. With the help of salt, such fish diseases as chylodonellosis, trichodinosis, tetrachimenosis, oodiniumosis, apiosis, are treated. In this case, the fish do either individual salt baths or add salt to the general aquarium.

In the treatment of fish in the general aquarium it is better to use rock salt. Salt solution is prepared at the rate of 1-1.5 tsp. Of salt per 10 l. aquarium water. Salt fish treatment is carried out at a water temperature of 27 to 31C. The filter is not disabled. Water is replaced in the usual manner.

For the treatment of fish in separate baths is recommended 1 tablespoon salt per 10l. aquarium water. To treat the fish in separate baths is a pain, but it seems to me that this method of treatment is much better tolerated by the fish, because the effect of salt is brief.

!!!Side effects!!!: salt from fish "ylozit" - they are spinning, rushing, etc., in addition, the fish begin to breathe heavily. Therefore, I advise you to carefully carry out such procedures. It is better to make the solution weaker, especially if the treatment is gentle, small or weak fish.

Tip: Do not repot the fish immediately after the salt bath in the general aquarium (this will only harm you). Gradually add clean water, to the state of "slightly salty", and then sit down the animal.

With the treatment of salt figured out ... you can add only that a weak solution of simple salt can also be used for the prevention of diseases of the fish. Especially if there are suspicions that, for example, new fish are contagious.

It is worth adding that some species of fish love salted water. Each species of such fish has its own salinity preferences. For example, tetradon likes 1 tablespoon of salt per 10 liters of water.

And of course, there is a special aquarium salt for the saltwater aquarium and saltwater-loving saltwater fish, but that's another story ...

ADDITION: Salt, sea - antiseptic and fungicidal agent. For many years, it has been used as a generally available and quite effective remedy for the treatment of many types of bacterial and some parasitic diseases of aquarium fish, and also as a prophylactic agent for keeping many species of live-bearing tooth-toothed ones. Applied for the prevention of fungal and bacterial infections. It is useful (in combination with elevated temperature) from many ectoparasites (skin and gill flukes), ichthyophthiriuses, in case of problems with the mucous membrane, decay, accidental damage to the skin and fungi. It is better to use coarse ground rock salt, cubed and crystalline sea salt, but only without any additives. You can not use iodized salt! Applied to treat Branhiomikoza, Gioza, gyrodactylosis, dactylogyrosis, Diplozoonoza, Kostioza, Kolumnarioza, Lepidortoza, Plistoforoza, Saprolegnioza, Sangvinikoza, ich, Hilodonelleza, Tetraonhoza, Trihodinioza and ectoparasites.
An increase in the salinity of the water causes additional mucus in the fish, which helps to eliminate minor infectious lesions. Some species of fish are well tolerated by salt (zhivorodki, East African cichlids, iris), Some species of fish, primarily haratsinovye and somovidnye, fighting and some invertebrate salt baths can not stand. For most representatives of the genera Corydoras, Thoracatum, Dianema, Brochis and Aspidoras, the maximum concentration is 1-2 grams per liter. It is especially harmful to arrange them long baths in the general aquarium with low salt concentrations. Ancistrus and other loricarides treat calmly with salt. Sumatran barbers do not like salt. Care should be treated with salt young labyrinth fish. Do not use salt in common ornamental aquariums with plants. Higher aquatic plants do not like high concentrations of sodium ions and chlorine, but the algae, which so maliciously spoil the entire design, they do not interfere with reproduction without measure. Regular addition of salt to the aquarium leads to water salinization. At the end of the treatment, the water in the aquarium is replaced in 2-3 doses. I want to once again draw the attention of readers to the need for an accurate selection of the concentration of saline. Guaranteed to kill all evil 4-5% solution, but a rare aquarium fish will hold on for even 1-2 minutes, not to mention the minimum required 5 minutes. But even 1.5-1.7% solution has a significant therapeutic effect. He is able to move almost all the fish within 10-15 minutes. With the urgent need for it, you can buy somics. As a rule, 2% solution is optimal (bathing time 10 minutes). Watch fish very carefully. If they start to push out of the water, they lie on the surface on their side and cannot go down, then the procedure must be urgently stopped. During bathing the tank with fish should be moderately aerated.
The temperature of the water should be raised in 2-3 days to 28-30 ° C with enhanced aeration. Dose 1-2gr. salts per liter for prevention, and for ingrained fungal and bacterial infections 10 g / l - this concentration is gradually achieved over 2 days, increasing every 4-6 hours by 0.1%. For the treatment of juvenile weakened fish, a less concentrated solution is used. If the fish begin to feel bad, you should immediately dilute the aquarium water with fresh distilled water. Treatment lasts 10-30 days. Bathing dose of 10-15 g / lna 20 minutes. Short salt baths are good for such diseases of aquarium fish as saprolegnosis, bone disease, oodiniumosis, chilodonellosis, trichodynosis, apiosomas, tetrachimenosis, gyrodactylosis, and dactylogyrosis. Specific means of dealing with them can be completely different, but rather high concentrations of salt kill them all. Salt is also used to neutralize nitrites, to combat the parasites Piscinoodinum and leeches. Leeching can be achieved by using short-term baths in a 2.5% salt solution.
Comment: Despite the availability of modern specialized drugs, table salt is still widely used in aquarism. In small doses and in the absence of sensitive fish can be used in the general aquarium, in large doses should be treated in a separate container.

Herbal medicine for fish and aquarium

PHYTOTHERAPY IN THE AQUARIUM It is no secret that aquarists use not only "aquarium chemistry", medicines, but also oak leaves, alder cones, and almond leaves for the well-being of fish.

Why does the water quickly grow turbid?

Muddy water in an aquarium with fish is perhaps the most common problem that concerns both beginners and experienced aquarists. Through trial and error, we have to figure out why muddy water appeared so quickly. The causes of this phenomenon can be different, ranging from a bacterial outbreak, improper feeding and irregular water renewal. A number of factors may also be the source of this problem. When the elimination or elimination of the causative agent of water turbidity in an aquarium occurs quickly, then the biological balance in the water is fully restored.

Sometimes this trouble provokes the death of fish, plants and invisible microorganisms. The first thing to do is to find out why the water becomes cloudy quickly. The second is to gradually eliminate the shortcomings.

Causes of Aquarium Water Turbidity

Why is the aquarium water quickly dimmed if the tank is equipped with a filter? The main problem is that on the very first day of the launch of the aquarium there is no holistic and permanent biological environment. The so-called "bacterial explosion" is caused by an active increase in the number of unicellular microorganisms that are constantly multiplying. In this case, the fish should not be settled, it is better to do it on another day. When microflora equilibrates in the tank, then the water will become crystal clear. Nothing serious needs to be done - this sediment will pass by itself. If you decide to change the water - it will again become muddy and unfit for life.

For 4-7 days the aquatic environment is fully restored, you can run plants and fish into it. To speed up the process, you can add water after the old aquarium with "residential" water.

Another common problem with the rapid turbidity of water in an aquarium is poor filtration of the reservoir. It should be well thought out system of purification, and this should be done quickly, until the young fish and did not have time to get used to a new house. A bad filter does not allow bits of dirt, feces, food debris, provoking the formation of decomposition products. Such rotten water constantly stinks and can cause diseases.

Watch a video about filtering water in an aquarium.

Why still water quickly becomes cloudy? If it has become an unpleasant green color, dimmed in a short time - it means that microscopic blue-green algae develop in it, which lead to the flowering of the reservoir. With good development of organic and strong light, they make themselves felt on the fifth day. When the light is not enough, cyanobacteria will acquire a brown color and begin to rot. Green color of the liquid with muddy, unpleasant smell - signs of growth of blue-green algae.

Aquarium water turbidity: action

If frequent water changes, the growth of bacteria and algae provoked the appearance of muddy water in the aquarium, some steps should be taken to eliminate the problem.

  1. If your aquarium is overpopulated, place the fish in different tanks, where they would be comfortable and spacious.
  2. If there is an excess of light, shade the aquarium by setting it in a secluded corner where strong lighting does not go.
  3. If the water becomes cloudy the next day after the first feeding, make a bottom siphon and feed the fish in small portions.
  4. Settle snails and fish in an aquarium that eat leftover food, clean glass and water in a tank. After a few days, the water will become free of dirt, and will not require additional replacement.

Wrong settlement of fish as a reason for the rapid turbidity of water

Why 2-3 days after the settlement of fish water became muddy? The fact is that for every one liter of water in the tank it is required to settle only one medium fish. If you run more pets, there will be problems with the pollution of the "house". Some fish plow the ground, and if there are many such individuals, it will turn into an underwater hurricane. Immediately move the fish in different aquariums, provide enough space for them. It is also important that they have enough oxygen, shelters and plants. In poor water oxygen to the fish can get sick.

In the aquarium with proper care and the right equipment, the water on the second day will not deteriorate. After running the fish, make sure that it adapts to the new environment. For 3 liters of water it is necessary to settle the fish size of 3-5 cm.

If the water is cloudy, you can use drugs that purify water from turbidity and dirt. After using them, water changes in the aquarium are not required for a few more days. They connect all the small particles that spoil the water until they fall into the filter. The next day, the entire bacterial cloud, small algae settle on the filter sponge, after which they can be removed.

These are the drugs: JBL Clearol, JBL Clynol, Seachem Clarity, Sera Aquaria Clear.

Watch a video about water changes.

How to change the aquarium water?

Full replacement of water is required only in the rarest cases, for example, with general quarantine or water poisoning. Why not do this procedure often? Because the day after the complete substitution, you will notice how the water turned cloudy again. A significant loss of its volume is stress for all inhabitants of the reservoir. Even during the death of some fish do not replace the water. But there are a number of recommendations, after studying which it is possible to understand why substitutions are necessary.

  • Substitutions are necessary after the introduction of pathogenic microorganisms;
  • Replacements are required after visible flowering of the reservoir;
  • Urgent water changes are necessary when a fungal mucus is detected;
  • Refresh water is required due to severe soil contamination.

You can add water to the tank as it evaporates, but not more than 20-30% of the total volume. It is best to update 1/5 of the aquarium once a week. After the procedure, the biocenosis will recover in 2 days. With the replacement of water cleaned the glass from plaque, remove debris from the bottom, clean snags and decorations.

It is better to plan a water change for both small and large reservoirs in advance. Type in a glass tank water from the tap, and leave it for a few days, covered with gauze. Chlorine and gas will evaporate, the liquid will be safe for fish. And it should be remembered that in the first week of operation of the aquarium the water is not changed until an ecosystem is formed in it.

About the aquarium. How to prepare water for aquarium fish?

Elena Gabrielyan

The aquarium is preparing to start a whole month.
First you need to check for tightness of the aquarium. To do this, you need to fill it up to the top with water and allow it to stand for 24 hours. located near a window or in direct sunlight, it is imperative to put a 7 mm foam under the bottom to level the bottom, because there is no perfectly flat surface anywhere. Then thoroughly rinsed (if bought at a pet store), or boiled for 2 hours if you typed yourself) the soil - its fraction should be 3-5 mm, poured into the aquarium half filled with water, it can be from under the tap, a filter with an aerator is installed (selected to your volume of aquarium) and a water heater with a thermostat, be sure to thermometer monitoring the temperature of the water and the operation of the water heater (the temperature in the aquarium should be 24-26 C) and left in working condition for a week. During this time, you decide on aquarium plants, whether they will be live or artificial, (decorations - grotto, snag, decorations - will also be selected), after a week you plant live plants (if you have planned), completely fill the aquarium with water (it should not be less than 3 days) - the filter should work continuously without shutting down (24 hours a day) and leave for 2 - 3 weeks to fully establish biological equilibrium. During this time, a colony of beneficial bacteria will settle on the filtering material and in the soil, and you will be able to determine the aquarium community, i.e., fish.
In the aquarium with a capacity of less than 50 liters fit
1. Guppies separately or together with Pitsiliyami
2. Aquarium with harazinki - Neon, Cardinals, Minor, Ternetsii, catfish - Mottled, Antsistr, Golden, Gastromizon
If the aquarium is over 100 liters then you can
1. Barbs - kept away from other fish
2. Angelfish, Gourami, Sword-bearers, Black Molia - you can keep each view separately or together
4. Goldfish - 1 fish should have at least 50 liters of water for a pair of 100 liters.
It is necessary to transfer the fish to the aquarium slowly over a period of 3 to 4 hours for the night, pouring half a glass of water from your aquarium every 20-30 minutes into the bag with the fish brought.
It is desirable to feed the fish with high-quality feed, frozen bloodworms, daphnia, Golden feeds with vegetable feed (like duckweed), dry food as an additive - adult fish 1 time per day, adolescents 2 times. 12 day a week full hunger strike (fasting day).
In addition, be sure to purchase a book on the care of the aquarium, it will be useful to you in the future. I recommend Kochetov, Gurzhiy.

Svetlana Tyushkevich

If you start a new aquarium - few days. Pour water, defend 3-5 days, plant the weed, put the equipment, and another day after 3 populate the fish. And if just for a substitution - then the day is normal.
If this is too long for you - there are special preparations in pet stores to speed up the process.
Here they advised to boil - in no case. Boiled water is dead. And in the aquarium you need to achieve a certain biobalance.

Victor dobroxod

When I was fond of the aquarium, I boiled, preparing the water in an enamelled tank. Then the water was settled for another day (at least half a day). Calcinates precipitated from the bottom of the water tank. Water softened in this way. If in your place of residence drinking water is “pumped” out of the ground, then it is better to do the same. Most aquarium fish are accustomed to "soft" water.
