Tests tap water & fresh or saltwater aquariums for carbonate hardness (KH). Can be used to determine the proper dose of pH buffers.
(KH) the measure of dissolved carbonate and bicarbonate ion concentrations, also called alkalinity.
Helps detect stress on fish caused by rapid pH shifts, the result of low levels of KH
Helps aquarists duplicate the natural habitat of their fish, thereby providing a healthy aquarium enviroment
