API KH Hardness Mini Test Kit

KH Test Kit.
Suitable for fresh and salt water.
Carbonate Hardness Test Kit.

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 vulnerable to disease. This kit measures carbonate and bicarbonate concentrations in the water. The proper KH level is an important part of the water quality and is necessary for the health of fish and the development and growth of aquarium plants. Tests tap water & fresh or saltwater aquariums for carbonate hardness (KH). Can be used to determine the proper dose of pH buffers.
