Test 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.
