This kit tests tap water and fresh or saltwater aquariums for carbonate hardness (KH), which is the measure of dissolved carbonate and bicarbonate ion concentrations. It helps prevent stress on fish caused by rapid pH shifts, the result of low levels of KH.
API's KH Carbonate Hardness Test Kit helps aquarists duplicate the natural habitat of aquarium fish, thereby providing a healthful aquarium environment. It can be used to determine the proper dose of pH buffers.
