General Hardness GH Test Kit Water Quality Aquarium Water

Product Description:

A simple test to check the total general hardness content in water.

GH (General Hardness) measures the calcium and magnesium in aquarium water. These minerals are important for both plants and shrimp. It is usually expressed as °dGH.

For aquatic plants

Calcium supports healthy new growth.
Magnesium supports photosynthesis and green leaves

For shrimp

Calcium helps harden the new shell after moulting.
Suitable GH supports healthy growth and normal body functions.
Unsuitable GH or sudden changes can contribute to moulting problems
