About this item

Best results are achieved by applying the treatment on dense floating algae mats. Consider the amount of vegetation being treated to avoid rapid depletion of oxygen levels, which can harm your fish.

99% Copper Sulfate Pentahydrate. To be used for large bodies of water, not small decorative ponds, water features, or pools.
Granular Copper Sulfate, 5 lbs
Controls most species of algae like filamentous, string algae and swimmers itch. Copper Sulfate should be used as a pond algae treatment on actively growing algae in water temperature above 60F.
