For Freshwater : General (GH) & Carbonate (KH) Hardness
The general hardness (GH) and carbonate hardness (KH) of aquarium water should match that of the natural habitat of the fish. Otherwise, fish will be stressed and prone to disease.
Since adding tap water increases the hardness of aquarium water, frequent GH and KH testing is imperative.
This kit measures both general hardness (GH) : the measure of calcium and magnesium in water, and carbonate (KH) hardness : the measure of carbonate and bicarbonate concentrations
Proper GH and KH levels are an important part of water quality and are necessary for the health of fish and the development and growth of aquarium plants
