How much to defend the water for the aquarium


How much to defend the water for the aquarium?

This issue has been considered repeatedly in the forums, in the reference literature, and it would seem that it does not make sense to discuss anew how much to defend and how to fill in the water during the next substitution. In most cases, the argument of the opponents is as follows: "the longer, the better the water", "let all the muck disappear," "a week is needed for everything to work out."

In this case, the aquarists are not in a hurry to justify these arguments, and water changes should be carried out regularly. Consider in detail the time interval for the preparation of water.

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.


The sedimentation of water gives the most pronounced result in the presence of solids. In accordance with sanitary standards, in their tap water should not be.

However, considering the quality of old water pipes (rust in pipes), maintenance of pumping stations by unqualified personnel and other factors, it is impossible to exclude the presence of solid constituents in drinking water.

If the plumbing is modern, made of plastic pipes and fittings, there will be no suspended solids in the water.

It is necessary to defend water until complete precipitation of solid impurities in the sediment is not more than a day, a further increase in the time of the result will not give.

Lime sediment on the inner walls of the kettle says that you have a high carbonate hardness of water and it manifests itself only when boiling. High rigidity is harmful only to certain types of fish. If it is necessary to lower it, then there are other ways to do it. Defending such water will not give any result.

If water is collected from a well, well or spring, the solids may be present in the form of clay particles or grains of sand, which create turbidity. Such a suspension for aquatic inhabitants is not dangerous. You need to pay attention to the fact that in its appearance it does not resemble clay milk (possibly contaminated gills in fish).

True, no one aquarist will use such water for his fish.

The presence of clay particles in the water gives a slime that does not precipitate quickly. Messing with cleaning is not worth it. To accelerate the achievement of full transparency, you can plant floating plants with a developed root system, it perfectly collects clay particles.

Summarizing the solids in the water, you can say:

  • Type water in any transparent container and leave it for several hours.
  • If there are impurities discussed above, then it will be noticeable after an hour (a precipitate will appear on the bottom, or pieces of rust).
  • In the presence of visible constituents of solid impurities, each time before the substitution, it is necessary to defend water (no more than 12 hours, further inefficient). In the absence of suspensions in water (and they are extremely rare), settling to remove solids is impractical.
  • Once a year we take water samples to control solids.

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.

Other gaseous impurities

If you pour fresh water from the tap, then you can observe a certain amount of bubbles on the walls of the tank. They are formed due to the presence of excess gases dissolved in water. When refilling fresh water directly into the aquarium, gas compounds appear on the plants, the skin of the fish, and the aquarium.

If the fish gets an excess of gas, then bubbles form in the circulatory system, which leads to blockage of blood vessels, gas emboli and, as a result, to death.

This can happen if the aquarium fish, bringing home, immediately settle into a container with fresh water. Beginners aquarists are always warned that it is impossible to do so!

Also, the appearance of bubbles can be caused by the method of pumping water into the water supply system. Cold water pumped into the pipes under high pressure loses it sharply at the exit, and the gases evaporate into the atmosphere. If you type this water in a glass, it will be covered in bubbles that pop up along the walls to the surface. It is necessary to defend a little.

With regular water changes in the aquarium, most likely, there will be no bubbles. Fresh and clean water does not greatly increase the number of gas-containing mixtures in the total volume, so you can not be afraid of the appearance of single bubbles on the fins of the fish.

From all of the above for gas mixtures it can be noted that:

  • chlorine poses the greatest danger;
  • upholding spend more than a day does not make sense;
  • in order to speed up the process of settling, it is necessary to provide strong aeration in the water tank (even simple mixing with a pump will significantly shorten the time for gas mixtures to exit);
  • For the use of fresh water (without upholding), you can add special components to it, which are very large in the sale, and after 10-15 minutes the liquid is suitable for adding to the aquarium.

Substances dissolved in water

The most dangerous components of water are dissolved impurities. They do not precipitate to the bottom, do not fly away into the environment and are invisible. Defending them does not affect.

There are a large number of such substances, and many are not classified. It is almost impossible to say exactly what harmful substances are in tap water without special chemical analysis. In addition, the composition of the water is not constant.

You can only say that in water with chlorine antibacterial cleaning there is a mass of liquid chlorine constituents (in the greatest amount of chloramine), which remain on settling. From this it follows that in the presence of chlorine water it is necessary to use special conditioners that will remove not only gas chlorine, but also bind chloramines.

In water, ammonia, nitrites, hydrogen sulfide may be present in large quantities. If the dose is large, the fish will suddenly become bad when changing water. An aquarium with advanced biofiltration (bacteria nitrifying) will transfer these harmful substances, and just launched can die.

The most unstable period in terms of water composition in the water supply is spring. Melting snow on the fields that were treated with various chemicals in the past season form streams flowing into reservoirs. And from them there is a water intake for the needs of the population.

Therefore, it is very important at this time of the year to process water for substitution with conditioners that bind nitrites, ammonia, chlorine, metals, etc. The choice of conditioner depends on your capabilities and the aquarium. This market is now widely represented. It is better to consult on this issue directly with the sellers.

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 much to defend the water for the aquarium

Having bought such a long-awaited aquarium and admiring fish that are floating slowly, each of the lucky owners of such a treasure sooner or later have a question about how much to defend the water for the aquarium and why? This question is not only incredibly important, but the life of the tiny inhabitants of the vessel depends on the correctness of the fulfillment of these conditions.

The importance of defending aquarium water

It is difficult to overestimate the importance of water settling in the aquarium. First of all, it is necessary in order to get rid of all kinds of parasites that may be in its composition. Since all microorganisms need living organisms for their vital activity, in this case the goal of the parasites can be fish. And at the time when the water is settled, next to each other, not a single living object is observed, which leads to the death of all sorts of microorganisms.

Also during this procedure occurs and the complete destruction of chlorine, which is also present in large quantities in water. And this is not to mention the possible saturation of moisture with various poisons or hazardous substances that begin to disintegrate only after a certain number of days. In addition, the settled water equalizes its temperature, which allows the fish to not feel any discomfort.

What should be done to reduce the time of settling water?

But if you follow all the rules, the water should be defended for at least a week, and sometimes life conditions and modern realities do not give so much time and then you have to urgently look for ways to speed up this procedure. In this case, special reagents, called chlorinators, are a great help because of their combination of chlorine and ammonia. With their use, literally within a couple of hours, the water will become completely ready for pouring into the aquarium. In addition, due to its diversity and accessibility, it is possible to purchase such reagents absolutely at any pet store.

In addition, the use of sodium thiosulfate is another way to reduce the time spent. These drugs are easily purchased at any market or pharmacy kiosk. But it is worth remembering that they are applied in the ratio of 1 to 10.

Prepare the water

As already mentioned, the quality of moisture directly affects both the environment of the aquarium and the level of comfort of its inhabitants, namely the fish. That is why it is necessary to clearly understand that the water flowing in the tap is completely unsuitable for replacement without prior preparation.

And first of all we check the quality of the water that flows in the tap. If it does not have an unpleasant odor and visually does not show signs of rust, then it is allowed into the vessel for the bay. But even here one should be careful and use only cold, but not hot water, in order to avoid chlorine and other conditionally harmful elements in the aquarium. So, they include:

  1. Solid, precipitated to the bottom.
  2. Gaseous type with the ability to evaporate into the environment.
  3. Liquid, dissolving in water and continuing to remain in it.

That is why you need to defend the water, so as not to give the slightest chance to affect the harmful bacteria on the life of fish in the aquarium.

Solid type impurities

The best result is water settling in the fight against solid impurities. Yes, and standards of sanitation indicate the complete absence of such elements in the water. But, unfortunately, the old water pipes and pipes that have been out of service for a long time, rare preventive repairs and unqualified personnel lead to their presence in the water consumed by people. It would be possible to avoid such a situation only if there is a plumbing pipe with plastic pipes. In all other cases, to completely clean the moisture you need to follow the following rules. First of all, the water collected from the tap is poured into a transparent container and left for some time (2-3 hours). After a certain time, a visual inspection is carried out for the presence of precipitated sediment and small pieces of rust. If such are detected, the water is poured into a new container and again left for a certain time period. Such actions are carried out until the water remains completely clean.

Gaseous elements

Unlike solid, gaseous elements, based on its name, evaporate into the air. But since they are combined with other soluble elements in the aquatic environment, they do not pose a particular danger to the fish. The method of water purification itself is quite simple. It is enough to take water in any of the weights and leave for a few days. Monitoring the volatilization of harmful substances is more expedient to carry out after 10-12 hours. So, the absence of chlorine is very easily determined by the change in the smell of water. If a specific aroma was felt before, then after the settling, it should completely disappear.

Soluble substances

One of the main hazards for fish, are substances that are completely dissolved in water. And the process of getting rid of them also carries with it certain difficulties. So, they do not precipitate and do not evaporate into the air. That is why in the fight against such impurities it is best to use special conditioners that can not only cope with chlorine, but also combine chloramines among themselves. You can buy them in specialized stores. It is also recommended to consult with the seller before buying. In addition, it is recommended to install a biofiltration system in the aquarium that can transfer these dangerous elements.

Water filtration

The process of settling water is recommended to be held once every seven days. But the replacement is best done not all of the liquid, but only only 1/5 parts. But besides upholding, there is another way to support a beneficial environment in an aquarium. And it lies in the filtration of water. Today there are several types of filtering. So, it happens:

  1. Mechanical Plan
  2. Chemical
  3. Biological

What you need to remember when defending water?

Based on all of the above, it becomes clear why it is necessary to carry out water sedimentation.But in order not to disturb the existing balance of the environment inside the aquarium, there are a few nuances to keep in mind. So, in the first place, the replacement of water in no case should not be carried out too harshly, thus risking to cause the strongest stress among the tiny inhabitants of the vessel, which can even lead to the most deplorable results. The replacement process itself must be carried out in parts and only after the complete purification of the soil.

Also, in the absence of a coating in an aquarium, after a while a thin film appears on it. Therefore, when it is detected, it must also be removed with a clean sheet of paper, the size of which should correspond to the size of the aquarium. To do this, gently put a sheet of paper in the water and lift it, holding the edges. If necessary, the procedure is repeated several times.

And most importantly, it should be understood that the cleaning procedure should be carried out without the use of any chemical agents and without making sudden and rapid movements, so as not to frighten the fish in any way.

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.

How to prepare water for the aquarium at home

Preparation of water for an aquarium is a crucial task that requires certain knowledge and skills, especially for a novice aquarist. The state of physical well-being of plants, fish and other animals living in water depends on the water used. Water properties are extremely important for creating a biological balance of a reservoir. To prepare water at home, you need to study the properties of water in order to properly adjust its parameters. In high-quality aquatic environment pets will live comfortably.

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.

See how to test the water.

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.

On the temperature of the aquarium water

As you know, all the fish and not only breed at a certain temperature of the aquatic environment. Heat mimics the rainy season, climate change, and the time of year, serves as a signal for finding a pair and spawning. All types of fish, snails, amphibians and reptiles live in different water temperatures. Also, residents of home nurseries are divided into two types - cold-loving and heat-loving. Heat-loving - those who live at a temperature not lower than 18-20 degrees Celsius, while cold-loving people are able to live in cool water (14-18 degrees and lower). The latter live only in spacious reservoirs, where there is a slow and cool undercurrent. Heat-loving species in cold water behave sluggishly, motionless, begin to ache.

Starting the preparation of water for the aquarium, consult with experts, or ask for help from the specialist literature. For each pet requires optimal water temperature, so only compatible animals need to settle in one tank with identical parameters (heat-loving animals are not settled with cold-loving animals, herbivores and predators are kept in separate nurseries, large and small are settled separately). In accordance with all parameters (permissible threshold of temperature, acidity, hardness), the acquired living creatures inhabit the aquarium. You should also take into account the conditions of the content of plants in the water, they are important specified parameters of the aquatic environment. Comfortable neighborhood will provide proper care and living conditions.

See how to prepare water for an aquarium.

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.

How long does it take to defend the water for the aquarium (tap water)?


Tap water for the aquarium should be defended for at least 2-3 days, so that the chlorine is completely out. But not in the light, otherwise the walls of the aquarium will quickly bloom and the water will become completely unsuitable for the aquarium.
For 4-6 hours, chlorine does not completely come out and in fish gradually from such water chlorine poisoning will begin with a frequent fatal outcome. Chlorine primarily burns the gills.
If you defend less than three days, on some sensitive fish appear white spots on the edges of the fins and tail. This is from chlorine. Neons and other sensitive fish are often subject to this. If the water will cost more than a week or two, then it starts to turn sour. It may appear bubbles when rocking the container. This water is no longer suitable for the Gulf, especially if it stood in the sun. To accelerate the weathering of chlorine can be put in a container of oxygen (from the compressor).
I have 5 aquariums and already had the sad experience of pouring water, settled less than 2 days. It is good that the fish did not die, and their fins and tails were only burned a little. Neons departed the longest. as they got the most, although besides them there were a lot of fish in aquariums. Crayfish and shrimps were not affected.

Olga White

What kind of garbage is written here by people who have never done a water analysis. As such, chlorine in water is not (chlorine - poisonous gas is heavier than air) Hypochlorides will decompose for months.
Water is defended to release the dissolved gases, mainly the NITROGEN of the air.
Accordingly, in winter, when the water is cold and the gas dissolved in the water is more - they stand for a day (we look at the vessel walls - as the bubbles cease to increase), in the summer - less. up to 4 hours.

How many days you need to defend the water in a 100 liter aquarium. before settling fish?

Maxim Onishchenko

to run the aquarium correctly
from pouring water in before planting fish, microorganisms need to be introduced into the water
for this
1. fill the washed soil (if you use the substrate as a substrate, then it does not need to be washed)
2. fill the water (you can pre-put a plate so that the soil is not washed out)
3. after 4-5 days turn on the filter, heater (compressor if available)
4. After another 4-5 days, you can plant the first plants (it is advisable for plants to spend two weeks in quarantine, so as not to bring some kind of muck into the aqua) ... turn on the lighting (first, do 2-4 hours a day, gradually increasing the day to normal 10 -12 hours ... an increase in time of 0.5 hours every two days)
5. after the plants have taken root, you can start the pioneers of the pioneers ... fish that are not demanding to the conditions of detention and water parameters (guppy just right)
6. 10-14 days after the first fish were planted, you can run the main inhabitants (do not forget about the quarantine ...)
This method has been repeatedly used ... and aquariums still stand today.
There is one more way to get started quickly (I ran a 90-degree aquas office three months ago) in one day ...
did not defend the tap water, but used the TETRA AQUASAFE conditioner (it is written on the bottle how to apply)
added bacteria ferment (used API cheaply and angrily ...)
Plants and animals were planted / launched within an hour and without quarantine, since they did not add anyone (the aquarium itself became a quarantine for them)
did not feed two days ...
and for three months there was no outbreak of algae or the mass death of fish (one fish was eaten when I was at the hospital, and the staff did not feed the fish (((well, this is discharge)
Conclusion ... both the first and second methods work and the next aquarium will be launched in a fast way (less hassle) ...
but in general, if you do not want to use chemistry, then tap water must be defended within 3-4 days ...

Elena Orlova

if for the first time you start an aquarium and you have small fish in the sense of not adults, but fry, then of course 2-3 days are already with the ground and algae, if the adults have enough fish for a day, and you can drop there methylene blue

How many days do you need to defend the water for the aquarium?

Shantal '

It depends on what kind of aquarium you have. Or rather, its volume ... I pour everything straight from the tap ... into everything. I have a total volume of all 600l aquariums need to be changed once a week to 20% of the total volume and where then to defend the water? !!! There are air conditioners for the preparation of aquarium water ... removing chlorine and heavy metal.


Since in our conditions it is almost impossible to find water with optimal characteristics, it is prepared by mixing waters of different hardness, boiling, demineralization, using plant extracts, chemicals and filtration.

Vlad Elbakyan

Well, water stopped to defend already 30 years ago, it is much easier to use special water conditioners. which instantly remove not only chlorine, but also bind various heavy metals and other harmful impurities. You drip some drops of such conditioner on a bucket and everything can be poured in a minute.
The most popular of the bottom are Sera aqutan and Tetra AquaSafe.
But there is no need to specially prepare water, mix, and so on :) This is required only in rare cases, for example, when breeding very rare and capricious fish. When you grow to such a level to breed rhodostomusy, then I will teach you how to properly prepare the water, but so far it is absolutely not necessary.
