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. Algae is an aquatic plant that can grow anywhere moisture, light and nutrients combine to support growth. You certainly can't control how wet your pond is; and there's not much you can do about how much sunlight hits the water. You can, however, avoid fertilizing near the pond or anywhere rainwater runoff may enter the water.
