Aquariums: how to change the water in the aquarium? How much to maintain water for the aquarium

There are three main questions that are asked by people who recently bought aquariums. How to change the water in the aquarium? How often do you do this? And, finally, how long to defend the liquid, to protect the fish from the effects of harmful substances? In this article, we will try to answer these questions.

The main thing that is necessary for a novice aquarist to master is that he does not breed fish or snails and does not grow algae, but contains a biological environment. This is not a cat or a dog for you. And not even a turtle. The aquarium is a closed ecosystem, all efforts should be directed to the maintenance of its vital activity. And in a healthy environment and the inhabitants live well.

Aquarium life cycles

If you pour water into the tank, even if it is stationary, you will not yet create a biological sphere that is comfortable for fish. Moreover, when released in such a sterile environment, many inmates may die from shock. First you need to put the soil, plant the plants and only a week later start the first fish. But even at this time it can not be said yet that the hydrobiological environment has fully formed. This condition is called in connoisseurs "new aquariums."

How to change the water in an aquarium of this type? Do this no sooner than two months after the start of the inhabitants. The substitution of water can slow down all the processes of establishing a balance, and in small containers, and at all will cause a catastrophe and the mass death of fish. Allowed a month later, drain 10% of water and fill to the same volume fresh.

New aquariums

How to change the water in the aquarium two or three months after the start of the first fish? The hydrobiological environment is still quite young. But already on the ground and glass can accumulate some deposits. Once every two weeks, use a special siphon to drain 10% of the liquid. If you do not have such an opportunity, it is permissible to change the water once a month, but then you need to update the 20% filling capacity. In the process of this procedure, do not forget to clean the primer and the glass. Also remove the faded leaves of the algae. Even if you have launched into the aquarium catfish and snails, there is no guarantee that they are fully able to cope with their task of cleaning bottom sediments and adhering to the walls. The question arises as to how to clean the ground if the water is not completely drained. We will return to this problem.

Mature aquariums

How to change the water in the aquarium during this period and when will it completely have a biological balance? This occurs about six months after the installation of the aquarium. And the more its volume, the more difficult it is to shake this achieved balance. Therefore, beginners are advised to start large aquariums (per 100 liters) so that they do not violate the water habitat by their inept actions . In this period of maturity, which lasts for up to a year, we just do that every month we change 20 percent of the liquid, along the way removing debris from the soil and cleaning the mucus from the panes. However, you need to carefully monitor that the water does not "bloom" (not green). With its regular cleaning, the eye of the crystalline transparency of the aquarium and the quickness of the fish inhabiting it will be enjoyed for a long time.

Old age: reboot

After a year and a half, the habitat in a closed capacity begins to degrade. To return her second youth, it is necessary to change the water every two weeks. Along with a regular update (at a rate of 20% of the total), you can from time to time practice the following procedure. It is for experienced aquarists is called "supersubstance." So, your aquarium is filled to the top with water. We merge 60%, clean the walls and add only 30%. The next day, remove half of the remaining liquid and add the same amount. This manipulation is repeated the next two days. And, finally, we top up the aquarium by 30% to the previous level. Thanks to the super-substitution, the concentration of harmful substances will decrease by 92%.

How to change the water in the aquarium

So, we examined the proportions that need to be adhered to, so that fluid renewal does not damage the biological balance of the living environment. But how to change the water? Specialty siphons are sold in pet stores (with a manual pear for air pumping or working from batteries), but these devices have a more budgetary alternative. Take the usual tube. Rubber hose is best not to use - rubber releases harmful substances. Optimal is a transparent tube made of polyvinylchloride. Wrap one end of it with a piece of gauze. Prepare a bucket - set it below the level of the aquarium. The tip of the tube with gauze dip into the water, and the second take in the mouth. Begin to draw in air until liquid comes up. Then, with a quick movement, lower the tip of the tube into the bucket. Water under the laws of gravity will flow from the aquarium into the tank. You can only control the amount. And the tip of the tube with gauze lead along the walls and the ground to remove the stuck dirt.

Water quality

The amount of liquid to be added is not the only indicator important for the health of the inhabitants. Qualitative characteristics - temperature, salinity (for marine fish) and water hardness in the aquarium - also have great significance. Sharp change of any indicator is a shock for the inhabitants. For tropical fish, the water to be added should be heated to a temperature 1-2 degrees higher than the one in the aquarium. The marine biosystem also needs to have the right fluid. To this end, in the distilled or reverse osmosis water for three days, the salts of NaCl, MgSO ₄ x ₇ H ₂ 0, KBr, SrCl ₂ x ₇ H ₂ 0, MgCl ₂ x ₆ H ₂ O, Na ₂ CO ₃ , KCI, CaCl ₂ , H ₃ BO ₃ , NaF and NaHCO ₃ .

How much to maintain water for the aquarium

It's no secret that we do not have fresh spring water from the taps, but a liquid in which almost the entire Mendeleyev table is dissolved. It's easy to notice, after a simple experiment. Collect a jar of water and see what will happen to it for several hours. First, gaseous impurities. It would be nice if it was oxygen. Although its overabundance is harmful to the health of fish. Vesicles through the gill slits penetrate the blood and can provoke thrombosis. But ozone, which in some cities is used to disinfect water, is a poison. The same undesirable elements are chlorine and its compounds. It's good that the gases leave the liquid quickly - enough hours. But the lime scale and rust, washed from old water pipes, settles on the bottom of the can after 12 hours. Dissolved impurities can be neutralized with special air conditioners (for example, Sera Toxivec). That's the answer to the question. For more than 24 hours, there is no point in defending water. All that could fall out of the sediment or evaporate, it already did. And then the water just begins to go out, harmful microorganisms are planted in it and dust comes in.

In what situations should the water be completely replaced

Only emergency cases - the massive death of the inhabitants or the global "flowering" of water - can cause the entire aquarium to be empty, disinfected and start all over again. But if the liquid does not yet produce a sharp unpleasant odor, the matter is fixable without a complete replacement. To remedy the situation, it is necessary to understand the reason why the water in the aquarium is green. Perhaps it's all about the wrong lighting. Then the situation will be corrected simply by rearranging the aquarium into a more shaded corner of the room. If the reason is the multiplication of primitive floating algae euglena, then you can buy live daphnia - this is harvesting green spirits, and feeding for fish. Also with pleasure devour euglena catfish, pecilia, mollynesia, snails. In pet stores, you can buy special chemicals from the rapid flowering of water.
