Applied Biochemists Cutrine-plus Granular Algaecide

A fast-acting, rapid-sinking granular algaecide that targets bottom-growing filamentous algae such as Chara and Nitella, as well as Hydrilla, in ponds and lakes. Visible reduction in algae growth is typically seen within 1-2 days of application; treated water remains usable for swimming, fishing, and irrigation.
