Ponds make beautiful, tranquil additions to your backyard or outdoor space, and API makes maintenance of clean and clear water easier than ever with API® POND ZYME SLUDGE DESTROYER, which quickly eliminates pollutants and restores healthy pond conditions using natural bacteria and barley.

We understand that each pond is a labor of love, and that trying to manage algae or other pollutants can make pond upkeep more arduous than necessary. With POND-ZYME SLUDGE DESTROYER, the only step you’ll need to take is measuring and pouring the dose to eliminate unsightly sludge from your water. Specially selected bacterial strains in POND-ZYME SLUDGE DESTROYER immediately begin working to break down fish waste and dead algae that cause any number of pond issues, from cloudy water to sludge build-up to debris that clogs your pump or filter. Over time, POND-ZYME SLUDGE DESTROYER reduces pond maintenance and helps keep your water clean and clear, so you can spend less time cleaning your pond and more time enjoying it.

True to our mission of “making a better underwater world,” POND-ZYME SLUDGE DESTROYER is a 100% natural product, and is completely safe for all pond fish, plants, and surrounding wildlife when used as directed. Please note that this product is for use in your controlled, man-made pond only, and should not be used in natural bodies of water with no outflow.

For dosing, we recommend two scoops per 200 gallons of pond water twice a week for two weeks at the very beginning of pond season, and one scoop per 200 gallons every two weeks thereafter for maintenance.

API POND-ZYME SLUDGE DESTROYER is an ideal algae and sludge solution for optimal pond health!
