Cloverleaf Absolute Clear is a 100% natural, fast-acting water treatment designed to rapidly clear green and cloudy water in ponds. This effective flocculent works by causing particles like algae and sediment to clump together and fall out of suspension, dramatically improving water clarity. It is a concentrated formula safe for all freshwater fish species. For ponds, it is recommended to use from spring and repeat twice per month to maintain clarity. The product works more efficiently with a pond filter system. Treats up to 22,700L (5,000 Gallons).
