Instructions and Recommendations

Why test for GH?

The general hardness of water is a measurement of the amount of calcium and magnesium salts present, with hard water containing more of these salts than soft water.

Tap water supplies have widely varying values of general hardness from 1 to 35 dH(degrees of German hardness) depending on which part of the country and world you live in.

The general hardness directly influences the internal regulatory functions of fish, plants and other organisms, but mainly affects the skin of fish and their eggs.

A suitable GH level for most tropical fish lies between 6 and 16 dH ( degrees fo German hardness).

The tetra test GH Kit was professionally developed to accurately determine the general hardness of your tap water and aquarium water.

To ensure optimum water quality weekly testing is recommended.
