The carbonate hardness (KH) or alkalinity of a water sample characterizes the buffering capacity, i.e. the ability to maintain the pH value of the water. The alkalinity in freshwater aquariums should not fall below 3 °dH. The optimum alkalinity level in freshwater aquariums depends on the species of fish and plants you are looking after. The Tropic Marin KH/Alkalinity Test is easy to use and accurate.
