FRESHWATER & SALTWATER

For Freshwater & Saltwater : Carbonate Hardness

The carbonate hardness (KH) of aquarium water should be tested frequently, since water with a low KH is subject to rapid shifts in pH, greatly stressing fish and making them vunerable to disease. The kit measures carbonate (KH) hardness, the measure of carbonate and bicarbonate concentrations in the water. The proper KH level is an important part of water quality and is necessary for the health of fish and the development and growth of aquarium plants.
