API POND ACCU-CLEAR Pond Water Clarifier quickly eliminates cloudy pond water caused by dirt, silt and floating particles. This fast-working pond cleaner works by aggregating tiny suspended particles in pond water to form larger clusters which fall to the bottom of the pond or are removed by the pond filter. API POND ACCU-CLEAR rapidly clears cloudy pond water and improves the efficiency of the pond filter. Exclusively for freshwater ponds, this solution can be used weekly or whenever cloudy water is observed. Be sure to use as directed for best results.
