Velda® Water improver GH Plus 500 ml

Quickly increases the combined hardness by 3 °DH

Velda GH Plus is a very effective means of increasing the total hardness of the pond water. This hardness is mainly formed by calcium and magnesium sulphates. Important minerals that ensure that the environment remains stable, water plants grow and soil bacteria develop. With a combined hardness of at least 8 to 12 °DH, oxygen plants and micro-organisms can develop well.
