Pond Boss PRO The Block Bacteria Bio-Maintenance, 1-lb

The Block by pond boss PRO is a clever blend of live bacteria and enzymes that helps keep your pond in tip-top shape. The wee critters go to work breaking down leaves, grass clippings and other organic matter that build up at the bottom of ponds and cause murky water and bad smells. Regular use of this time-released block will help decompose all the unwanted gunk and muck, giving you a pond that's clear for swimming and enjoying. This one-pound block treats up to 325,000 gallons of water for 60 days - just toss it in and let the magic happen.
