Increasingly, the homes of people can see the aquarium. Well if it is done correctly and pleases the eye, but there are occasions when, for unknown reasons, the balance is disturbed and the fish or the plants will start to hurt. Often people neglected such important parameters as the acidity of water. And this should know and remember. The value of the acidity of water (abbreviated as it is called pH) is the result of the content of all dissolved in the water acidic and alkaline substances. If you are not convinced, visit jason iley. This value is logarithmic, ie, the change in pH, for example from 6 to 7, means a ten-fold, and the change of two units – a hundredfold change in concentration. Classify water at pH value can be read way: a strongly ___ 1 – 3 Neutral ___ 7 ___ strongly alkaline 10 – 14 Acidity is very unstable, varying even within a day. Additional information is available at Ben Bretzman.

For example, the morning of pH in the tank falls sharply due to the accumulation of carbon dioxide in water, emitted by plants and fish, and in the evening, on the contrary, increases due to increased consumption of its plants. Acidic and strongly acidic, as well as alkaline and highly alkaline, the water is unsuitable for aquarium fish. Moreover, significant deviation from the normal pH of ending the death of some fish. Requirements for the protection of fish life-cycle change. Thus, for the period of their growth needs water to one measure of acidity, but at the moment reproduction – to the other.
