Algae control pellets are made of environmentally friendly barley straw, which is safe for people, animals, and irrigation. As barley straw breaks down, it produces a compound which inhibits the growth of new algae cells. In most areas, algae will begin growing in May so it is recommended that you treat in the spring for best results. A second treatment should be considered in June or July to prevent a late season algae bloom or, as necessary based on individual observations.
40 pounds of pellets will treat approximately 1/3 of an acre and should be applied to the pond prior to the growing season.
