What kind of water suitable for the aquarium?

In aquarium practice is usually to use tap or well water, which in its properties is very diverse. Water is oxide of hydrogen (H2O) and consists of two parts hydrogen and one part oxygen. In the water many dissolved substances (oxygen 21%, nitrogen 76%, carbon dioxide of 0.3%). Water in contact with soil, plants, fish, the products of decay and alkaline earth elements, acquires new qualities. The water in the aquarium must be free of any impurity metals must not contain large amounts of salts of magnesium, calcium and any other components that are harmful to aquarium inhabitants.

In rural areas often use wells, river and lake water. Before pouring water in an aquarium must be heated to a temperature of 70 C, thereby partially release water from undesirable microorganisms.

Water, potable, and suitable for the aquarium, of course, if it’s not mineral water. At home to fill in the most suitable aquarium tap water, which in most geographical areas of our country is of medium stiffness with seasonal fluctuations within 8 – 12 ‘. Excessive chlorine in it, you can delete, defending water in non-metallic container for 1 – 2 days (complete disappearance of released bubbles), active aeration (10 -12 hours),filtration through activated carbon, adding to it the hyposulphite (thiosulphate) sodium (1 g/10 l) or by boiling for 10 minutes. The last method, the water loses oxygen and must be aerated.

The use of pond water is not recommended, and the water is rain and snow the city is not suitable for the aquarium, as it contains large amounts of harmful solid, liquid and gaseous state. In rural areas, the use of such water is possible, but it needs to be filtered from dust and other substances. Continue reading
