- General & carbonate hardness test kit
- Monitor GH & KH to create a more natural habitat
- For Freshwater aquariums
The Freshwater Hardness GH & KH Test Kit helps detect stress on fish caused by rapid pH shifts, which result from low KH levels and helps aquarists duplicate the natural habitat of their fish.
