How (and How Often) to Test Aquarium Water for Healthy Fish and
Water hardness is a measure of the dissolved mineral content of water. There are two types: the general hardness (GH) and carbonate hardness (KH). When keeping freshwater fish and plants, the GH and the KH of aquarium water should match their natural habitat. The GH & KH TEST KIT helps aquarists duplicate the natural habitat of their fish, as well as detect low KH levels, which can lead to rapid and wide pH shifts, stressing fish. Tip: KH can strongly influence pH.

Salicylate test measures ammonia levels in both fresh & saltwater aquariums. Ammonia, the #1 killer of tropical fish, is continually produced in the aquarium from fish waste & uneaten fish food. This API test kit measures ammonia levels from 0 to 8 ppm. Why test for Ammonia? Tropical fish continually release ammonia (NH3) directly into the aquarium through their gills, urine, and solid waste. Uneaten food and other decaying organic matter also add ammonia to the water.

Most water problems are invisible to the eye. Quickly measure and modify the six aquarium levels that are most important to the health of your freshwater fish. To stay healthy and thrive, fish need properly balanced levels of ammonia, pH, high range pH, nitrite and nitrate. These levels can change rapidly and create harmful conditions when fish waste, uneaten food or other organic matter accumulate, or when untreated water is added.
