GH & KH TEST - General & Carbonate Hardness

This kit provides a complete testing for water hardness - both general (GH) and carbonate (KH) hardness.

The general hardness and carbonate hardness of aquarium water should match that of the natural habitat of fish, otherwise fish will be stressed and prone to disease.

Since adding tap water increases the hardness of aquarium water, frequent GH and KH testing is recommended.

For fresh water aquariums.
