All fishponds, koi ponds and water gardens have organic matter buildup that creates unsightly sludge. The matter is created naturally by dead algae, decaying plants, uneaten fish food and fish waste. As sludge begins to decompose, it consumes oxygen and reduces water quality. Sludge is also a breeding ground for fish disease.
Natural pond bacteria does not eat sludge quick enough to control accumulation, but PondZyme Plus helps to quickly break down pond sludge converting the sludge into harmless minerals. For better water clarity use in conjunction with Accu-Clear pond water clarifier (wait 24 hours after application of Accu-Clear to add Pond-Zyme Plus). 16 ounces treats 16,000 gallons.
