What water should be poured into the aquarium


What kind of water to pour into the aquarium. What water is needed for an aquarium

Water is a living space for aquarium plants and fish. And besides taking care of the presence of the necessary bacteria, the level of ammonia and other substances in it, we must also think about the various properties of water. After all, they contribute to the development or inhibition of the life processes of the inhabitants of the aquarium. Let's find out what water is needed for an aquarium

What water is needed for an aquarium

Novice aquarists do not always understand what kind of water to pour into the aquarium. Let's understand the composition of the water. Water varies in acid content in it. PH is an indicator of the level of acid. Acidity has a significant effect on biological processes in the aquarium. Water consists of acid and alkaline ions, the number of which determines the measure of acidity. If they are in equal shares, then the water is considered neutral. In this case, the pH equals 7. If the figure is lower, this is evidence of acidic water, if higher - alkaline. For the successful development of fish and plants in the aquarium should be normal water.

One of the parameters of water is its hardness, which affects the possibility of keeping fish in water and depending on the amount of calcium in it. Stiffness can be temporary and permanent. Constant hardness is observed in water after boiling. The rigidity value for aquatic inhabitants may differ from the value in natural water bodies.

For the maintenance of fish, it is important to maintain a certain rigidity in the aquarium and take into account the fact that calcium is gradually absorbed by plants and fish, while the rigidity decreases. You can increase it by adding chalk, shells, limestone, as well as soda and magnesium chloride to the aquarium.

In the development of fish plays no small role light exposure. Duration of daylight hours is necessary for them from 8 to 10 hours a day. Light can be natural, artificial and mixed. Near the window the aquarium will receive natural light. In the fall and winter, it is desirable to use mixed lighting. Artificial lighting is used to a greater extent when breeding fish.

Also on the body of aquatic inhabitants affects the water temperature. Moreover, each type of fish requires a certain temperature limit for normal life. Therefore, acquiring this or that fish, it is necessary to find out at what temperature it lived in the same place.

How often should water be changed

Inexperienced aquarium owners usually completely change the water once a month, which has a very negative effect on fish. Late replacement is also not very useful for both fish and filtration systems. Experts advise to change the water in the aquarium often, but in small quantities. You can do this twice a week for 10% of the total amount of water.

Water preparation

It should be remembered that new water requires preparation. It is necessary to monitor the level of chlorine, defending water for about a day. It is also required to level the temperature and salinity of the new water with the parameters of the one in the aquarium.

And remember, before you begin the procedure of replacing water, you must disconnect the aquarium from the electricity and thoroughly wash your hands from contaminants that can harm the fish.

How to run the aquarium for the first time?

It is decided that we will have an aquarium! He has already been selected and purchased, the equipment is waiting for the coolest next to him in beautiful boxes, the bottom is already filled with bright red brilliant, terribly spectacular soil, and there is a ceramic crocodile on it that will blow bubbles. Now we pour water and, while she stands up for an hour or two, let's go to the pet shop and buy the best fish there - those with long fins, and other yellow ones with red dots (whatever they are called? However, it doesn't matter, the main thing is beautiful) ...

Stop! No matter how commendable is the desire to join the fascinating world of aquarism, this process should not be forced, otherwise the first experience may be so deplorable that one does not want to continue. Let's tolerate a little more and see what should happen to a glass jar full of water in order for it to become an aquarium.

Aquarium is a balanced biological system in which many living organisms coexist. These are not only fish and plants planted by the host, but also self-inhabited small invertebrates, protozoa, algae, bacteria. And in order for the aquarium to be beautiful and comfortable for life, the whole system must be in balance. Substances entering it from the outside should be processed without deteriorating the vital indicators of water and not causing death or, on the contrary, uncontrolled outbreak of the number of any inhabitants, and then removed from the system during water changes and cleaning the aquarium.

What you need to do before launch?

Even before the launch procedure, it is necessary to solve a number of critical issues and take some necessary steps:

  1. Decide what kind of fish or aquatic animals you want to have. Find out what conditions they need. Be sure to find out if they are compatible with each other!
  2. Depending on the decisions on the first item, choose the volume and model of the aquarium, as well as a list of necessary equipment and design items. Based on the species and number of future inhabitants, decide whether you need a heater with a thermostat, for example, how powerful the filter should be, whether an additional compressor is needed, how to decorate an aquarium: stones or driftwood, which plants to plant, and so on.
  3. Choose a place for the aquarium - not in the draft and not in the sun. It is also important that access to the aquarium was convenient, and there were a sufficient number of outlets nearby.
  4. Buy and install an aquarium (necessarily on a flat surface, so that its edges do not hang from the shelf or pedestal even per centimeter). Pre-aquarium washed without the use of chemical detergents.
  5. Place the equipment in the aquarium: filter, compressor, heater and thermometer, lighting. Fill the soil with a layer of 3-4 cm. Depending on the type of soil and its source of origin, it may be necessary to pre-heat it, boil it or rinse it. The same applies to stones and snags.

Now the aquarium is ready to fill up with water and start running. But before we give a step-by-step start-up instruction, let’s try to figure out what this notorious launch is for and what the running aquarium is different from the one that is not running.

Quite a bit of theory

As we already wrote above, the aquarium is an open-loop system, where various substances come outside. This is mainly fish food, which the fish eat, while releasing waste. In chemical terms, ammonia is the most significant and toxic part of this waste; even in low concentrations, it can cause poisoning and subsequent death of fish and other aquatic animals. However, in nature there are bacteria (they are called nitrifying) that consume ammonia, oxidizing it to nitrite. Nitrite for fish is not much better than ammonia, but there are other types of nitrifying bacteria, which in turn bind them, turning them into relatively harmless nitrates.

This whole system of bacterial colonies, which makes water with nitrates from poisonous ammonia water, quite suitable for fish, is called a biofilter. Since the efficiency of the biofilter directly depends on the number of its constituent bacteria in the aquarium (it is clear that two or three microscopic nitrosomonas cannot convert ammonia, selected by a dozen large goldfish, into safe compounds), these bacteria must be allowed to multiply to the desired number. For this they need three things:

  • nutrition (ammonia and nitrite);
  • substrate (surface to which they can attach);
  • and for some time, as bacteria multiply rapidly, but still not lightning.
And now, finally, we will formulate what the launch of an aquarium is: this is a set of measures that allows the biological filter to mature and begin to work fully. Or, in other words, cultivation in the aquarium of such a number of nitrifying organisms, which will be sufficient for the processing of ammonia and nitrite, allocated by all the inhabitants of this aquarium.

Run (instructions for beginners)

So, we will analyze the points, how to run the aquarium correctly:

  1. The run starts with water pouring. Water must be poured plumbing, pre-defend it is not necessary. After pouring water turn on the filter with aeration. If the filter does not have an aerator, then the compressor must additionally work, since nitrifying bacteria require a lot of oxygen and a heater (set at 24-25 °). In this form, with the lights off, the aquarium is left for 5-7 days. All these days they spend only monitoring the operation of the equipment: check whether oxygen is supplied, measure the temperature of the water.
  2. After 5-7 days, unpretentious fast-growing plants are planted, after which they turn on the lighting for 4-5 hours a day.
  3. After 1-2 days you can start the first aquarium animals. This may be small unpretentious fish (viviparous or, for example, danios), but it is better to use snail ampoules or hymeno-viruses that are more resistant to water quality. There should be few animals. Feed them once a day in very small portions. It is necessary to constantly monitor their behavior and appetite. Ampulyaria, for example, are excellent indicators of water quality: in clean, good water, they rush around the aquarium at cruising speed, straightening antennae and looking for food. At this stage, the light is turned on for the whole day (8--12 hours), you can add special bacterial cultures to the aquarium to start (they are available from different companies, for example Sera Nitrivek).
  4. After a week, the remaining plants are planted and begin in parts (at intervals of 1-2 days) to launch the main fish population. For each released party you need to carefully monitor, feed moderately.

That is, in fact, all science. True, nothing complicated?

Of course, the equilibrium in the aquarium is still unstable, and some time after the launch such unpleasant phenomena can occur, such as outbreaks of diatoms. But if the launch was carried out correctly, these problems are usually not catastrophic, do not lead to a massive freezing of fish and are solved in working order. To combat these diatomies, for example, a small charming catfish otozinclus is successfully used.

How to facilitate the process of starting the aquarium?

Above, we wrote that for the reproduction of beneficial bacteria need nutrition and substrate. And, of course, the initial number of the bacterial colony matters. Thus, in order to accelerate the maturation of the biofilter and, accordingly, the launch of the aquarium, you can immediately add a significant amount of bacteria to the artificial reservoir and prepare a large area substrate for them (there is enough nutrition for bacteria in the starting aquarium).

Bacteria are introduced with the help of industrial starter culture (we also mentioned about them above) or with water, soil, filter filler from the existing, safe aquarium. To ensure a sufficient area of ​​the substrate for bacteria, it is recommended to use filters with fillers made of porous ceramics or filters of considerable volume with other fillers, plant plants with narrow, feathery leaves, and use fine gravel of even size as the soil. All these surfaces will inhabit nitrifying bacteria.

Startup control of the aquarium greatly facilitates the use of tests for aquarium water for ammonia and nitrite. These tests are produced by different manufacturers and are not uncommon in pet stores. With their help, you can track the level of these toxic compounds in the water and adjust the population of fish in the running aquarium.

As you can see, the correct launch of the aquarium takes not so much time - it is quite possible to suffer two or three weeks. It does not require a colossal amount of strength and special academic knowledge. But it helps to avoid many problems in the future, preserves the life and health of the fish, and therefore, the nerves and good mood to their owner.

Water change in the aquarium, what kind of water is needed for the aquarium?

How much water should be defended for the aquarium?

(water preparation)

Let's talk about the questions asked in order:
In order for chlorine to evaporate and a 24-hour excess of dissolved oxygen will be enough to keep the tap water. The maximum water for the aquarium defend 14 days. This should be done in a bowl with a wide neck.

I note that in pet stores sold a large number of specials. preparations for adaptation of tap water (for example, AquaSafe from the Tetra series, etc.). In addition, these drugs have additional additives that improve the quality of aquarium water. I strongly recommend using them.

Frequently asked questions: About changing aquarium water, for example, is it possible to replace aquarium water (1/4 volume) with undisturbed tap water?

- You can do nothing terrible (one thing, but: it should be about the same temperature as in the aquarium, do not pour ice water from the tap). But still, if you are a caring owner or fish are expensive ... Do not be lazy to defend the water.

When changing aquarium water, always remember that old water is always better than fresh water. In many sources, they talk about the need to replace the weekly aquarium water to fresh. Personally, I disagree with that. Since the older the aquarium water, the better it is configured biological balance. I replace the aquarium water in my aquariums about once a month and I think that this is quite enough. For ten years aquarium management "complaints" from aquarium fish on this issue have been reported.

Making conclusions and summing up, I emphasize:

- Frequent change of aquarium water is not needed!

- The frequency of changing the aquarium water to fresh depends on the volume of your aquarium. The larger the aquarium, the less need to replace the aquarium water.

- The change of aquarium water can be carried out with non-settled water (up to 1/5 parts). But not desirable !!! )))

- The turbidity of the aquarium water after the replacement with fresh - direct evidence of a violation of the biological balance in the aquarium. (clouding will pass by itself, in 3-5 days).

- Answering the question what kind of water is needed for an aquarium and fish? I will say, the "old" is better than the "new". If the water is green, dirty or muddy - use aquarium coal and other specials. drugs. In addition, consider the specifics of your fish. For example, discus - very picky to the conditions of detention and require frequent replacement of the new "super quality water" and high temperature.

- When carrying out a complete change of aquarium water (restarting the aquarium), pour into the container and leave at least 1/3 of the old water. Exception, disease and quarantine aquarium!

- Changing the aquarium water should follow the "cleaning of the aquarium", and not vice versa.

I recommend also to read the article. AQUARIUM WATER from which you will learn about the qualitative components of aquarium water and methods for balancing them in the home.

Andrey Kovalenko

"first you need to buy an aquarium and wash it for a week", but why :)? To extend the fun launch of the aquarium :)
ANDREY ANDREYEV, as I understand the most banks yet, then I will begin:
1. Better to buy an aquarium of at least 50 liters
2. Next, you will need to buy a filter (but better, of course, a pump with a sponge): so that the water in the water mixes, and it is necessary so that the temperature in all water layers is the same, as well as to saturate the water with oxygen, also on the pump sponge beneficial bacteria accumulate (so now you understand that this equipment is mandatory for an aquarium !!)
3. Thermometer: so that you always know what the temperature of the water in the aquarium
4. Thermo heater: necessary to raise the temperature of the water in the aquarium (but you can not buy it if you have a temperature in the room where the aquarium will stand, the temperature does not fall below 24 degrees)
5.lamps (I have energy saving with a temperature range of 4200K (this spectrum is well suited for living plants)), lamps are necessary for living plants, if artificial plants are planned, then you can take with a temperature spectrum of 6400K (under this spectrum, the fish look beautiful)
6.Grunt: it is best to buy the soil with a fraction of 2-3 mm. A layer of soil is better so that there is at least 3-4 cm, then let's talk about launching the aquarium:
1. Place the substrate under the aquarium at the place where the aquas will stand (you can make the substrate of foam)
2. wash the aquarium with warm water and a sponge
3. wash the purchased soil in the bucket (so that there is no dirt left in the soil), you can boil it (but I did not do it)
4. we fill in water from the tap to half akvas
5.Fill soil (washed in a bucket) in the aquarium
6. install the equipment (pump with a sponge, thermometer, thermal heater (if necessary)), turn on all this equipment after you have completed step 8
7. Set the scenery
8. fill the water to the end
9. The next day we plant live plants in the ground.
10. Turn on the lamps (the lamps must be switched on at least 9 hours a day, but for the first time no more than 4-5 hours, otherwise we can’t avoid algae) after 4 you can run 2 somics (preferably corridors, resistant somiki ... checked by me :))
12. A few days after launch, the water will cloud, so do not worry, after a while the water will become clear.
13. 2 weeks later you can run any fish you want (well, of course those that are suitable for your volume)
Attention!! ! Immediately start a lot of fish should not be (fraught with a bacterial outbreak, and therefore the death of your population in aquas)
Then talk about the care of aquas:
1. We do not change the water in the first month after the launch of the aquarium at all (do not change the month !!!)
2. After that, it will be necessary to change the water once a week at 20-30%
3.After you run the fish in the aquarium they should not be fed for 2 days (this is due to the fact that the fish must adapt to your aquas)
4. further it is best to feed the fish (young 2 times a day, adults once a day), and arrange a discharge day once a week (i.e., not feed at all once a week)
5. Also, as long as you still have not grown plants, it is necessary to siphon the soil (once a week) in places where the plants are not planted.
6. clean the glass as needed (you can clean it with a scraper, or you can do it yourself as described on the site //
"2. After this, it will be necessary to change the water once a week at 20-30%" - at this point I forgot to write that the water must be defended for at least 9 hours (it is necessary for chlorine to disappear from the water), (I do so : I pour water into a bucket (10 liters) and leave the water to stand overnight, then pour water from the aqua (hose) into another (empty) water bucket, then pour (with a bucket :)) waste water into the aquas)
Well, for the care of aquas I kinda wrote everything :)
Good luck in the aquarium!

Elena Ivasenko

Buy an aquarium, filter or compressor, thermometer - to measure the temperature in the aquarium, the water heater - to maintain a certain temperature in the aquarium - from 20-26 degrees, each fish needs its own temperature, the optimum is 24.Water defended. Then buy soil, plants and fish compatible between by myself.

11 quick tips for a novice aquarist
If you have recently taken a great interest in aquariums and decided to create a small piece of wildlife in your home and put your first aquarium - this article is for you. In it, I tried to give a few basic tips that you will need when starting your first aquarium.
1) Do not immediately buy a small aquarium, take at least 60-80 liter, if, of course, at home there is a place for it. Larger aquariums are more resistant to temperature and chemical changes. Recently, the trend is for nano aquariums (aquariums up to 20 liters), but it is better to start with a larger aquarium.
2) Wash the filtering elements of your filter only in aquarium water (not in the aquarium itself), for example, in a bucket or basin, this will allow you to save those bacterial colonies that in turn help you in the fight against ammonia and nitrite. Tap water can kill them, which for some time will disrupt the biological work of your filter.
3) Do not forget and do not be lazy to replace every week 20-25% of water, this will allow you to fight with nitrates in your aquarium. And remember that you should not, as 80% of people in our country thought, pour out all the water once a year and boil the soil, it’s enough to replace 20-25% of the water with fresh water, which will ensure a long and happy life of your aquarium.
4) Do not overfeed fish, it is very important. Firstly, overfeeding harms the fish itself (here you can look at people, overeating was not good for anyone), and secondly, the food that was not eaten starts to rot in the aquarium (the smell of the swamp), which significantly spoils the water quality.
5) Always check the compatibility of the purchased fish. You must admit that nobody saw an open-air cage with wolves, penguins and rabbits living together in a zoo. In the aquarium just as well.
6) Do not release a new fish from the bag or bottle directly into the aquarium, first place this bag in the water to even out the temperature, then add 50-100 ml of water from the aquarium into the bag, the bottle - this is done in order to level the parameters water. It is better to do this alignment within 20-30 minutes, no less.
7) Before buying fish, inspect it very carefully for damage, cloudiness, sores and other abnormal condition.
8) Use the quarantine aquarium for newly arrived fish, this will help to keep the fish that you already have. The question is especially acute when the fish is not cheap, and in any case, the fish after some time become full members of the family and we, aquarists, need to take care of their health. So just in case keep a quarantine aquarium where you can watch a new fish for a couple of weeks for its health.
9) Run the aquarium consistently, so as not to overload the filtration system. The filtration system as a human body, if it is trained gradually, it will give a greater result than if you immediately give a greater load. Colonies of bacteria develop gradually with increasing load, so do not immediately run all the fish that you have identified yourself.
10) Do not believe the rule of 1 cm fish = 1 liter of water, who invented it and when, but this rule is not entirely correct.
11) Do not get carried away using chemicals, especially if you do not fully understand their effects and the consequences of their use.
It is worth remembering that the path to success in aquarism is through scooping up new and new information through books, magazines, forums and aquarium portals that help us to succeed in our hobby.


Modern aquariums are assembled on silicone, so that they are fully ready for work and do not need to be washed. Install an aquarium with the necessary equipment, fill it with water, turn on the aerator, heater, filter. When the water warms up, you can land the plants. Let the aquarium work without fish for two weeks. And only then you can run the fish.

What water should be in the aquarium for fish?

Natalia A.

Water and must grow turbid at the start, everything is properly filled with water, wait until the biological balance is established, the water itself will be cleaned, the fish should not be planted at once, otherwise the flash may destroy it, for small volumes the substitution is necessary.

Dasha Knyazeva

Most aquarium fish will suit 22-26 ° C. Perhaps only discus and some labyrinth fish prefer water warmer: 28-31 ° C. Goldfish need water more cool. When the aquarium content of the temperature range of 18-23 ° C, they are quite satisfied. For quite a long time (a year or more) they can live at 25-27 ° C, but eventually they get sick - as a rule, they develop dysfunction of the swim bladder.
It is important to avoid significant (more than 2-4 degrees) temperature fluctuations. Its smooth changes are quite permissible, but sharp jumps during a day, or even several hours, are extremely undesirable. Meanwhile, this happens not so rarely, especially with small aquariums with a capacity of less than 60-50 liters. Relatively small volumes of water cool quickly and heat up quickly. For a long time, the open window in the cold season can easily draw a room. If there is no heater in the aquarium, then in a few hours of such aeration, the water in it will noticeably cool down. It turns out the fish, too, can catch a cold. And then "pick up" a bacterial infection or chylodonellosis. If there is no thermometer in the aquarium, such temperature fluctuations may go unnoticed by the owner of the aquarium. It should be noted that a small aquarium is immeasurably smaller than even a small natural reservoir, where water temperature changes proceed much more slowly (large masses of water slower and cool down and heat up more slowly). That is why fish are completely unsuited for sudden temperature jumps and these jumps can cause them great stress.

What kind of water to fill in the aquarium?


If you want to quickly run the fish in the aquarium, you can do the following ...
Lay the soil, at least 3 cm thick (natural biofilter). Then pour the water settled overnight (from the tap), for example - 10 l. and add to it the "old water" - at least 25% (2.5 l), which you take from friends from the aquarium. "Old water" must be taken from the "clean" aquarium in which the fish live and live. Then the biological regime of microorganisms in your tank will be balanced and the water will not dim. You can immediately run the fish, and add the rest of the water as your water “grows old”, in small portions (3 liters, for example) at intervals not earlier than in a week. The surest way! Keep fish for over 20 years. You can still buy in the pet store specials. means for artificial aging of water (I do without it)

Olga Pulkina

water must be poured over the water! it should be a little warm so the fish won't freeze! By the way, never hold an aquarium in the window, the fish will freeze, they will die! before you start a fish, buy a compressor, otherwise slaves will not live without it!


For the first launch of the best is the version with water from the tap. You lay the soil in the aquarium, then fill it with water and leave it for 3-7 days (depending on the water properties in your area), then you plant the plants and run the fish. If the plants are unpretentious and a large volume of the aquarium, then they can be planted immediately (pour 1/3 of water, plant the plants and add water).

What kind of water to pour into the aquarium: boiled, or from the cold tap, and then stop? Or immediately from the tap warm?


When you start the aquarium, I pour cold. I install the heater, after heating the water I turn on the filters. Well, where to defend 250 liters? Then I never change the water. When moving unless. Substitute and topping up. It is possible from under the tap, but I have several bottles of 8 liters per battery, topped up after siphoning and as it evaporates.

Ptenchik 777

Water from the tap is suitable for the life of fish and plants, but it must be defended for 3 days in plastic, glass or enamelled dishes with a wide neck. During this time, chlorine and other gases will evaporate, which disinfect tap water. Each time, changing the water in the aquarium, fresh water must be defended.

What kind of water do you need for an aquarium for a red-eared bug? Boiled or tap

Vint t

Accommodation: An aquaterrarium of 100–150 liters, filled at least 20–30 centimeters in water, serves as a home for a red-eared turtle (it is necessary that the turtle can roll over with little effort if it suddenly turns out to be on its back). A prerequisite is the presence of a stalk over which incandescent lamps and a UV lamp (for example, Repti Glo 5.0) will be installed, which are so necessary for heating, preventing diseases and growing turtles. It is advisable to build an inclined (from the bottom) stalk with a rough, but not scratching surface, located 20-30 centimeters from the upper edge of the aquarium, otherwise the most active individuals can simply get out and run away. On land, you can pour the soil, provided that it will not pour in the water.
Water should be clean and warm enough (26 - 28 ° C). It is necessary to change the water as it is polluted, but at least 1-2 times a week. If you install a filter turtles, then care for turtles much easier. However, the water, even if it turns out to be completely clean, still needs to be completely changed once a month. The air temperature on the island should be in the region of 29-30 ° С.
