API Pond Algaefix effectively controls green water algae blooms, string or hair algae (Cladophora), and blanketweed (Oedogonium) in ponds containing live plants and fish.
Registered with the EPA, this algae control is fast-acting, controls algae growth, controls the formation of new algae, and helps resolve algae problems in water gardens, ponds, and ornamental fountains containing live plants and fish. It is only suitable to use in synthetic-lined ponds and fountains, not for use in earthern-lined ponds (such as clay).
CAUTION: DO NOT use with freshwater crustaceans including shrimp, crabs, and lobsters.
IMPORTANT: Do not overdose. If dealing with additional pond issues, such as sludge, use the Algaefix on its own first until the algae is under control before using any other bacterial cleaner.
