When keeping freshwater fish and plants, the general hardness (GH) and carbonate hardness (KH) of aquarium water should match their natural habitat. The API® GH & KH Test Kit helps you duplicate the natural habitat of your fish to prevent stress, keeping them healthy! The kit includes 2 bottles of liquid reagent, 2 glass test tubes with snap-tight caps, and step-by-step instructions.
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!
