GreenClean Granular Algaecide


GreenClean Granular Algaecide is ideal for controlling string algae and algae blooms in ponds, waterfalls, fountains and streams. It works through oxidation and breaking down the algae cells on contact. When used in a pond the dead matter floats to the surface where it is removed by a skimmer or a net. Available in several size containers.
