SANCO COPPER SULFATE Pond Algae Control Size:5 lb naturally occurring microorganismsCrystal Blue Copper Sulfate is a great pond algae control product for filamentous or string algae. Copper sulfate should be used as a pond algae treatment on actively growing algae in water temperature above 60F.

Copper sulfate is safe for most varieties of fish (see restrictions below)
