Tests saltwater aquariums for 4 important water conditions: high range pH, ammonia, nitrite and nitrate.

Liquid test solutions accurately measure aquarium GH and KHMonitor general hardness (GH) and carbonate hardness (KH) for stable aquarium pHTest and monitor tap water to ensure proper aquarium water parametersTest tap water and freshwater aquariums for general hardness (GH) and carbonate hardness (KH). These two water parameters help maintain stable pH crucial for a healthy aquarium environment. Use to detect and prevent rapid pH shifts that result from low KH levels. Monitor aquarium GH/KH to maintain ideal water parameters. For freshwater.Please click on "More Information" for directions for use.
