Tetra Test GH

Tetra Test GH. The Tetra Test GH measures the total hardness of aquarium and pond water accurately and reliably.
The total hardness (GH) of the water is formed by various ions such as magnesium and calcium. The GH value influences the health of fish, plants and, above all, the important microorganisms. The ideal GH value for ornamental fish is between 6 and 16° dH.
The test offers good, long-term stability and a wide range. It is suitable for freshwater and saltwater aquariums and ponds.
