Fritz Algae Clean Out

Fritz Algae Clean Out is a highly concentrated, EPA-registered selective algaecide formulated to rapidly eradicate nuisance string algae, blanketweed, and green water (single-celled algae blooms) in freshwater and saltwater environments  Unlike heavy-metal treatments, its copper-free formula targets unwanted algae growths without causing harm to live aquatic plants, reef corals, or biological filter bacteria  Added directly near high-flow filter outlets, it works quickly to restore crystal-clear water clarity without altering pH levels  Note: Not safe for use with freshwater invertebrates such as snails, shrimp, clams, or crustaceans
