Every year at this time, lakes and ponds get a fresh onslaught of algae that can turn your favorite swimming hole into a greenish cesspool. If you don't want to cancel your picnic or fishing trip, you're going to need to treat the water with an algaecide like Crystal Blue Bio-Clear. One gallon of Bio-Clear will treat up to 1.5 million gallons of water, so it's enough for 4 acres of water 4-6 feet deep. The best part about Bio-Clear is that it's safe for plants, animals, humans, and aquatic life. You can use it for the lake, pond, or ditch maintenance. Allow for 90 days for the full cleaning experience!
