      Measure the general and carbonate hardness of your aquarium water with the API GH/KH Hardness Test Kit.

      Key Features
      • There are two types of water hardness, general hardness (GH) and carbonate hardness (KH) which is measured by the amount of dissolved minerals in the water.
      • The API Hardness Test Kit measures both types of water hardness in your freshwater aquarium.
      • KH levels should mirror that of the fish or plant's natural environment, and very hard water can cause a white crust to form in parts of the aquarium.
