The total hardness (GH) constitutes the amount of dissolved magnesium and calcium salts in the water. If the volume of these salts is low, the water is referred to as soft water, if the volume is high, the water is referred to as hard water. The concentration of these salts in the water affects the organic functions of the fish and plants. Therefore, it should be tested on a regular basis. The Tropic Marin GH-Test is accurate and very easy to use.
