Copper Sulphate

Controls and prevents algae growth in pool and reservoir water.

Distinctive blue crystals used as an algaecide in pools and open water storage. Copper is effective against the types of algae that chlorine alone struggles to clear, particularly in warm weather when growth outpaces routine sanitising. It is also used in reservoirs and tanks where algae would otherwise establish on the walls.
