Velda VT GH Plus 7,5 L 142034

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 pond solution is a very effective means of increasing the total hardness of your pond. The solution consists largely of calcium, magnesium sulphates and other important minerals to ensure that the environment remains stable so that growing plants and soil bacteria can develop unhindered. This amount of VT GH plus (15 L) is suitable for treating 90.000 liters of pond water.
