Carbonate hardness test kit
Monitor KH to prevent pH problems
For freshwater aquariums
APIs 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.

The proper KH levels is an important part of water quality and is necessary for the health of fish and the development and growth of aquarium plants.
