Tetra Pond Peat&Straw Extract 250ml Water Care Treatment

It prevents excessive solar radiation and thus the growth of algae. The water takes on a natural, darker colour thanks to the high-quality humic substances. It contains pure, natural vegetable active ingredients derived from peat and barley straw extracts. Suitable to use throughout the year. Particularly recommended in spring when the metabolic activity of higher plants is still too low.
