GH & KH Aquarium Water Test Kit Freshwater Hardness Testing

The GH & KH Test Kit provides a simple and reliable way to measure general hardness (GH) and carbonate hardness (KH) in tap water and freshwater aquariums. Monitoring these key parameters helps aquarists maintain stable water chemistry and create conditions suited to their fish.

Testing GH allows you to understand the overall mineral content of your water, while KH testing measures buffering capacity. Adequate KH levels help prevent rapid pH fluctuations, reducing stress on fish and supporting a more stable aquatic environment. Regular testing also assists in replicating the natural habitat conditions required by specific species.

Please note the outer box is damaged; however, the contents remain suitable for use.
