Api Liquid Gh And Kh Hard Test Kit

API Liquid GH And KH Hard Test Kit. Tests tap water and freshwater aquariums for general hardness (GH), the measure of dissolved calcium and magnesium ion concentrations, and carbonate hardness (KH), the measure of dissolved carbonate and bicarbonate ion concentrations.
Helps in detecting low KH levels, which can stress the fish by causing rapid pH shifts, and helps owners duplicate the natural habitat of their fish.
