Even at low temperatures, algae can usually grow faster than plants. The application of AlgoRem blocks the first algae surge in spring. Not compatible with sturgeons. Mode of action: The active ingredient molecules of AlgoRem attach themselves to the algae cell wall and bind firmly to it. The cell wall tears open and the algae is killed. The dead algae residues with the attached active agent molecules are microbiologically degraded. Compatible with aquatic plants, fish and microorganisms when used properly. Reliable effect within a few days. The use of Tetra Pond AlgoSchutz and Tetra Pond PhosphateMinus is recommended to prevent algae. Particularly easy and precise to dose.
