Product description:Schurocos POND-stable for a stable KH value in the garden pond.Schurocos POND-stable is the ideal means for regulating the carbonate hardness in the garden pond.The carbonate hardness is one of the most important factors in all waters. In general, water with a carbonate hardness between 4 and 10 dKH is considered ideal. Ponds with a carbonate hardness of less than 4 dKH are considered treacherously unstable. There is a risk of acid collapse here. This means that when the sun is exposed to strong sunlight, biological decalcification occurs and the pH value rises above 9, which can cause the death of all fish and other pond creatures. With Schuroco ́s TEICH-stabil, the PH value increase is also delayed. Application:for: Garden pondsAgainst: pH fluctuationsProperties:biodegradable no influence on sewage treatment plantsInstructions for use:Mix Schurocos POND-stable in a large container (e.g. a clean bucket) and add to the pond. Observe dosage. Run the pump or move the water in any other way. All filters, including UV filters, can remain in operation.3 kg for 50,000 litres (with an increase of 2 dKH).
