Specially selected bacterial strains in Pond Zyme Plus immediately begin breaking down fish waste and dead algae that cause cloudy water, sludge build-up, and debris that clogs pumps and filters. Through natural nutrient competition and enzymatic action, Pond Zyme Plus reduces pond maintenance and keeps pond water clean and clear. Pond Zyme Plus is a 100%-natural product, safe for all pond fish, plants and wildlife.

Pond-Zyme Plus is a heavy-duty pond cleaner, containing five specially selected bacterial strains in a stable dry form. Pond-Zyme Plus breaks down fish waste and dead algae that can cause cloudy water, sludge build-up, and debris that clogs pumps and filters. Organic matter accumulates in all garden ponds producing a build-up of sludge and causing cloudy water. The five strains of bacteria in Pond-Zyme Plus digest sludge into harmless minerals and water, visibly improving water clarity and quality. Pond-Zyme Plus helps pond filters stay cleaner longer, reduces pond maintenance and keeps pond water clean and clear.
