Crystal Blue Copper Sulfate, 15Lb

Crystal Blue Copper Sulfate, 15Lb

Crystal Blue Copper Sulfate Crystals (15 lb) is a pond algae treatment intended for use on actively growing algae when water temperatures are above 60°F. This granular copper sulfate can be applied by broadcasting crystals, dragging crystals in a burlap bag behind a boat, or dissolving and spraying—with the recommended method being to dissolve in hot water and spray directly onto algae. To help prevent oxygen depletion, it’s important to treat only 1/2 of the pond at a time, and this product should not be used in ponds containing koi, goldfish, or trout.
