Why Test for KH (Carbonate Hardness) & GH (General Hardness)?
Tap water rarely provides the water conditions necessary to maintain an optimal aquarium. Some tap water supplies have very low KH (below 3 odKH) which has very little pH buffering capacity. This can contribute to wide pH swings in the aquarium. Also, when water evaporates, it leaves behind hardness ions. Topping off with tap water simply adds more minerals to the aquarium, resulting in a steady increase in GH. It is therefore necessary to test the GH and KH frequently to monitor water quality and prevent stressful conditions from occurring.
