Velda VT GH Plus 3,75 L 142033

Maintaining the water hardness (GH value) is very important to allow your fish and plants to grow and develop and to provide them with a stable living environment. However, biological processes in the pond can reduce water hardness. An ideal hardness is between 8° and 12° GH. The Velda VT GH plus water improvement additive is a very effective way to increase the total hardness of your pond. The solution mainly consists of calcium, magnesium sulphate and other important minerals to ensure that the pond environment remains stable, so that growing plants and soil bacteria can develop freely. This 7.5 L VT GH plus is suitable for treating 45.000 liters of pond water.
