API GH & KH Test Kit API Increase in dissolved oxygen concentrationTests tap water and freshwater aquariums for general hardness (GH) and carbonate hardness (KH). Helps detect stress on fish caused by rapid pH shifts, which result from low KH levels and helps aquarists duplicate the natural habitat of their fish. KH & GH Test Instructions: What is Carbonate Hardness (KH)? Carbonate hardness (also known as alkalinity) is the measure of carbonate (CO32 ) and bicarbonate (HCO3 ) ion concentrations dissolved in water.
