API POND ALGAEFIX algae control effectively controls green water algae blooms, string or hair algae (Cladophora), and blanketweed (Oedogonium) in ponds containing live plants and fish. API POND ALGAEFIX algae control is fast-acting, controls algae growth, controls the formation of new algae, and helps resolve algae problems. Registered with the EPA, API POND ALGAEFIX algae control controls many types of algae in water gardens, ponds, and ornamental fountains containing live plants and fish.

To ensure accurate dosing, determine pond volume before use. Do not overdose. Add 1 teaspoon (5 ml) for each 50 gallons or 0.25 cup for each 600 gallons of pond or fountain water. Thoroughly mix into pond water by adding near the pump outflow, waterfall, or aeration device. It can be mixed in a bucket and dispersed evenly around the pond. Repeat dose every 3 days until algae is controlled. Once algae growth is under control, add one dose per week. Weekly doses will control algae growth and reduce pond maintenance. CAUTION: DO NOT use with freshwater crustaceans including shrimp, crabs, and lobsters.
