Tests fresh or saltwater aquariums for carbonate hardness (KH)
The API® KH Carbonate Hardness Test Kit tests fresh or saltwater aquariums for carbonate hardness (KH), and helps monitor water quality and prevent invisible water problems that can be harmful to fish and plants. Carbonate hardness stabilizes aquarium pH, and can be used to determine the proper dose of pH buffers.
We recommend that you take a few minutes each week to monitor your aquarium conditions and create a better underwater world for your fish. Testing your aquarium water has never been so easy or accurate!
