How to control the water in an aquarium?

You must constantly watch over the water in your aquarium. It is not an alternative. This is an obligatory crossing point. This watch consists of testing the aquarium water by looking at certain characteristics. In doing so, you comb through the inconvenience caused by poorly maintained water on fish and also plants. Water is an essential element for your aquarium and it is for this reason that knowing it is essential. Yet you wonder how to get there? We are committed to helping you effectively in this article through our practical advice. They will allow you to control the water in your aquarium.

Controlling the hydrogen potential (PH) of aquarium water: ideal for ensuring the quality of the water in your aquarium

Testing the PH of aquarium water is of great importance and all the best aquarists know it. It is a test that allows you to measure the degree of acidity of water. When you know the acidity of your water, you will limit the death of your fish. Moreover, not all species live with the same level of acidity. However, when you have a PH value lower than 7 then your water is acidic. Basic water is that whose PH is greater than 7 and so-called neutral water has a PH equal to 7. It is necessary to know these characteristics of water so as not to be unpleasantly surprised. It is urgent that you adapt a specific PH to your water because an unregulated PH is a source of serious trouble for fish. A slightly rising PH even if it doesn't have to be is better than a plummeting PH. The neutral PH is more widespread in the maintenance of the water of the aquarium unlike the others. The main thing is to have an idea of ​​the different elements of your aquarium's ecosystem in order to guarantee them a specific PH every morning. And this, after daily measurement or perhaps twice a week based on the various existing tests. It must be done urgently as some neglected internal factors can cause loss of control.

Controlling water hardness: a tip for a livable aquarium

In this main step, you will use two clues to do the job. It is a job at the end of which you have a clear overview of all the minerals available in the water. These two indices are the total hardness (GH) and the carbonate hardness (KH). They both allow you to know what your fish will be fed. The GH index favors the determination of a portion of carbon-free minerals. Thanks to it, you will know if your water is hard or soft. Imagine there too that you have the GH you need for your aquarium. Because each species evolves with its GH. The GH of some species should not exceed 5, for example. Thus, your water will be considered average if its GH varies between 11 and 16. On the other hand, hard water has a GH which is above 15. The last type of water going in this direction is water soft with a GH of less than 10. As for the carbonate hardness index, it provides a utility function on the PH by reducing its offensive effects. As its name suggests, KH treats carbon-bearing minerals and promotes PH buffering. In addition, you should not be mistaken about the denominations GH and KH which are also available in French. These are German degrees that you will find in French by converting.

Testing the dose of nitrites and nitrates in your aquarium water: a method not to be trivialized

It is also one of the best methods to make aquarium water suitable. This is a task to accomplish every week for a good comfort for your aquarium. Of course, your aquarium will be made up of plants and fish that need to be fed, but the food of one can be detrimental to the other. This will mean that while nitrates are known to be beneficial to plants, fish suffer if they reach a certain amount. The nitrates present in the water mainly appear following the decomposition of organic elements of all kinds. This can be dead fish, leaves or leftover food. They are therefore to be watched closely since they go so far as to guarantee the arrival of algae. It is useful that you limit the nitrate concentration of your water to a value not exceeding 50mg/l. This exempts you from having to deal with fish without immune defenses.
As for nitrites, they are very dangerous for the aquarium. They are to be avoided as much as possible so as not to run the risk of an aquarium without fish. They occur when fish excrement undergoes transformations and deprives the fish of oxygen. It will be necessary to keep its content as low as possible, that is to say less than 0.2 mg/l. If you find that the rate is rising, check for excessive food or poor filter performance. The fish would then begin to float on the surface of the water. If necessary, the renewal of a good part of the water is necessary to evacuate any impurity.

Checking Water Temperature: A Safe Way to Better Water

This rule is important to follow. When a species changes its living environment, it is preferable that it finds itself in the same conditions as before. When this is respected, it can survive happily. This is why you must work on the temperature of your water so that it is similar to that enjoyed by your fish. The temperature of tap water can be evaluated for this purpose to know which poison to choose. The control of the water temperature of the aquarium is beneficial and must be preceded by that of the fish.


Your concern was to control the water in your aquarium, we have just provided you with some tips on the matter. By respecting them, we are convinced that you will take full advantage of them. These are carefully developed tips that do not put you in difficulty. Try them out and be sure to give us some feedback.
