What water can not be poured into 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.

Watch the video on how to change the water in the aquarium.

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 putrefactive and pathogenic bacteria to multiply. If high-quality and proven water is poured into the tank, all its inhabitants can be healthy.

Water for aquarium

Water is the source of life and habitat of all marine and freshwater creatures. Under natural conditions, animals feel comfortable mostly in clean water. In such water, they can grow and multiply. At home, everything is different. Many people prefer to start aquarium fish, but not all care about the proper quality of water for the aquarium. The use of ordinary tap water can be detrimental to its inhabitants. Therefore, there are several simple rules for preparing water for an aquarium.

What kind of water to pour into the aquarium?

Fish and other inhabitants of the aquarium should not be run in fresh water. It is fraught with diseases in animals. Various chemical compounds that are in the usual for us water, are detrimental to the inhabitants of the aquarium. Chlorine is especially dangerous. Water, without fail, must be separated.

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.

Aquarium water temperature

The most suitable temperature for aquarium water is room - 23-26 degrees. In winter, the aquarium should not be carried out on the balcony, nor is it recommended to place it near the radiator or heater.

Water hardness in the aquarium

Stiffness is an important parameter of water in an aquarium. This parameter is determined by the total amount of calcium and magnesium salts that are dissolved in water. The range of water hardness is very wide. Under natural conditions, this indicator depends on climate, soil and season. Fish can live in water of different hardness, but they are extremely necessary for magnesium and calcium salts - they play an important role in the growth and reproduction of animals.

In an aquarium, the hardness of the water is constantly changing, it becomes softer - the fish digest the salts that are in the water. Therefore, the water in the aquarium should be periodically changed.

Aquarium water purification

The easiest way to clean is a complete change of water in the aquarium. But in some cases this task is difficult and unnecessary. Water is much easier to clean. As a rule, simple filters based on activated carbon are used to purify turbid water in an aquarium. Water filters in the aquarium can be made independently or purchased at a pet store.

Aeration of water in the aquarium

This parameter is regulated by temperature, plants and the presence of living things in the aquarium. By aeration, oxygen is monitored in the aquarium. Aeration can be performed using special devices - compressors that saturate water with oxygen. Also, there are filters for water treatment with built-in compressors. Water parameters in the aquarium play an important role in the normal functioning of fish. It is important that any of the parameters be changed very smoothly, excluding sudden temperature fluctuations.

By following these simple rules, each owner of the aquarium provides fish with conditions as close as possible to the natural ones. And this, in turn, is the key to the health and long life of pets.

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.

What kind of water to pour into the aquarium ????

Bronskaya Evgenia

Tap water needs to be boiled, water added to the aquarium should be no higher than room temperature. Just tap water can be defended day in an open vessel and calmly add to the aquarium.

Elena Alekseeva

Good day!
Under no circumstances should water be poured into the aquarium !! ! Your fish will die from chlorine! It is necessary to defend the water at room temperature in banks, 2-3 days, then pour into the aquarium and pour into it more specials. means for additional care of water, and at the same time well-being of your pets)


A settling day in a plastic container (which would not oxidize) is during the subsequent replacement of a part of water.
And if you purchased a new aquarium and want to start it, then the water should be prepared for 2 weeks. You can add a TETRA VITAL type preparation to it, it contains a biotope necessary for the life of the fish. Gradually plant the aquarium with plants, then, if desired, with snails, and only when the characteristic smell of fresh marsh, characteristic of aquarium water, appears, then the first test fish (which is not very sorry if anything ...) can be put in there. And all this time there should be filtration and aeration in the water, even at the launch stage, when no one is there yet. Good luck.

Aquarists: I know that it is impossible - but nevertheless, is it possible to pour water from the tap into the aquarium, and immediately run there ...


There are special liquids in pet stores. Still, it is better to let the water settle and settle down to the plants. Mom herself would be nice and interesting to let go of the fish. But this is also done not immediately, but gradually: 1-in a vessel (better package) with a fish, add half a glass of water from the aquarium
2-package with fish put in the aquarium * in order to normalize the temperature in the package. after 15 minutes
3-again in the package add water from the water., And after 15 minutes. once again add half a glass of water from the aquarium. Wait 15 minutes, now we are releasing fish in aqua. Good luck! And do not forget: "Hurry up, make people laugh!"
Pace. water-25 degrees is desirable. today you will do everything with gravel and water, plant plants with your mother on Wednesday, and release the fish all together next weekend.

Zdohnut ... if the way when it can be done after some time (how many hours I do not remember) tetra start
But it is better to defend the water, but it will be a complete disillusionment in the aquarium.
Before you can fish in a new aquarium, it takes three to four weeks to create the necessary biological environment. During this time, useful microorganisms settle and multiply in an aquarium, without which it is impossible to establish the biological equilibrium necessary for both fish and aquarium plants. Otherwise, if there are not enough nitrifying bacteria in the new aquarium, the level of ammonia and nitrite can reach too high a level that is dangerous for all inhabitants of the aquarium.
Now everything is much simpler ... TetraAqua® SafeStart is a revolutionary result of many years of research. With Tetra SafeStart you can populate the aquarium right away! TetraAqua SafeStart creates a biologically active natural environment that allows you to immediately populate the fish in a new aquarium. SafeStart contains the patented live bacteria Nitrospira.
Until now, it was widely believed that the bacteria Nitrosomonas and Nitrobacter were nitrifying in the aquarium. However, Tetra's research has shown that these bacteria can only be active in wastewater, but not in an aquarium, where ammonia and nitrite can reduce bacteria only from the Nitrospira family. Thus, to launch a new aquarium:
Place the desired soil and plants in your tank (for example, the Tetra AquaArt Discover Line aquarium).
After adding TetraAqua AquaSafe, which binds heavy metals and chlorine in water, add TetraAqua® SafeStart. In this case, please observe the dosage indicated on the label.
Then you can run the fish, as TetraAqua SafeStart provides immediate biological activation of your aquarium.
BioExtract enriches water with vital substances found in the natural environment: iodine to provide fish with vitamins, magnesium for growth and health, and vitamin B against stress. The content of organic colloids in AquaSafe provides additional protection for the sensitive mucous membranes of fish, and BioExtract helps reproduction of beneficial bacteria for clean and healthy water.

Nick whiteraven

you shouldn’t risk ... all the fish will die due to the presence of chlorine in the water ... although there are known cases that everything was done ... some aquarists suggested that if, for example, in a 10-liter aquarium, 5 liters of boiled cooled water were poured in the fish will not feel the difference ... but this is not true, even if the fish are cut in half the water will be in danger ... so do not risk ... take pity on the fish ...


If the fish are not very capricious (guppies, swordtails) you can do this:
heat the water strongly, but do not bring to a boil, cool to 27-28 degrees, add specials. solution (sold in a pet store), after 4-5 hours you can land the fish. But the result is not always successful. It all depends on the quality of the water. Good luck.

Romantic you have a father. Great. But you should be friends with your head too, and you feel sorry for the fish. And if you give your neighbors a pair of buckets of water? And in the morning to collect. Agreeing with the neighbors is a cool surprise. Still, the fish will have more chances. And to begin to pick up unpretentious fish. Try it!

Vlad Elbakyan

Not the best option, but if illy pressed, then you can. For such cases, there are special water conditioners for removing chlorine and heavy metals from it - Sera aquatan, Sera cholvec, Tetra AquaSafe.
You dial cold water, level the temperature by pouring boiling water from the kettle (gently, do not fall on the glass! Burst!). Hot tap water is undesirable.
After equalizing the temperature, pour in the conditioner, stir and let stand for 30 minutes. You can’t immediately spit the fish. It’s best to mix the bag with the fish and pour water from the aquarium there for half an hour. This will equalize the pH values ​​and avoid acid shock. And this is the most common cause of the "incomprehensible" death of fish after buying from dummies.
But keep in mind - after such an express start of the aquarium, the water in it is dead, the microflora did not work out. After a day or two, the water will turn sharply cloudy and then it will constantly get cloudy for at least six months. At normal start, the aquarium is started first, let it stand for a week until the dregs pass and then the fish are planted.
In general, do not say that I did not warn you.

Is it possible to pour drinking water from a store into an aquarium?


Do water changes regularly?
Drinking water contains at least irregular ph and substances unnecessary for fish are added. Use regular tap water (just let it stand for about 24 hours). All water can not be changed, only a part (maximum a 1/2, and preferably 1/5 of the volume, but several days in a row). You can buy water at the pet store.
Also special conditioners are sold there that help to cope with ammonia, ammonium, nitrates and nitrites or incorrect ph. And tests to understand that with water, and take the right air conditioner in the right quantity (ph, by the way, you can change the folk methods, only you need to know it).
Here that is not so with water happens: //
ps: read that instead of settling, you can warm the water to 40-50 degrees and cool. I did not try it myself, but if everything is critical with you, you can take a chance.
