Tap water rarely provides the water conditions necessary to maintain an optimal aquarium. Some tap water supplies have very low KH (below 3 odKH) which can contribute to wide pH swings in the aquarium. Also, when water evaporates, it leaves behind hardness ions. Topping off with tap water simply adds more minerals to the aquarium, resulting in a steady increase in GH. It is therefore necessary to test the GH and KH to monitor water quality and prevent stressful conditions
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!
