Captain Liquid Copper Algaecide is the right tool for economical and fast-acting control of a broad-spectrum of filamentous algae and planktonic algae.

Captain is a chelated copper product that is effective on both filamentous and planktonic algae in a wide range of fresh water applications. Algae control occurs in 3 to 7 days following a Captain application and there are no restrictions on treated water, even immediately after use for swimming, fishing, watering livestock, irrigating turf or ornamental plants.

The mode of action for Captain is uptake through the algal cells where the copper ion inhibits photosynthesis providing a fast-acting result.

*Apply Captain anytime algae is present. Apply Captain at a rate of 1 to 2 gallons per surface acre. When determining the amount of Captain to use, consider only the area that is covered in algae.

Mix 32 ounces Captain with 2 ¼ gallons of water, spray onto only ¼ to 1/3 of the surace area of the pond at a time. Treating all algae across the entire surface area at one time can cause oxygen depletion and result in harm to your fish. For severe algae infestations, limit treatment to 1/3 of the water surface when the water temperature is between 65°F and 85°F. The remaining two 1/3 fractions of the body of water should be treated at 7 day intervals.

Captain is most effective when it is applied in bright, early morning sunlight under calm conditions when water temperature is at least 60°F. Apply at the first sign of an algae bloom, if possible. Algae control will occur in 3 to 7 days following application. Larger mats should be broken apart before treatment with high pressure water or a flat tool. Retreat when regrowth appears.

Contact with algae will be improved by breaking apart heavy surface mats before application. Use Cide-Kick II to increase penetration and contact. Add Bio Boost Enzyme to the Tank Mix to increase the effectivness of the algae treatment. Treat heavy infestations in sections to avoid oxygen depletion.
