Direction For Use
Apply Captain algaecide 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 1/2 gallons of water, spray onto only 1/2 to 1/3 of the surface 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 a total pond algaecide that’s 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.
