Copper Sulfate Smart Crystals 5lb Sanco

Copper Sulfate Smart Crystals are the perfect solution for eliminating filamentous or string algae. At water temperatures of 60F or higher, it is safe to use on most varieties of fish (with some restrictions). This product is best applied in three ways: broadcasting, burlap bag dragging, or hot-water spraying. We particularly suggest dissolving the crystals in hot water and then spraying the actively growing algae. Remember, always treat just half of the pond to prevent oxygen depletion due to algae death!  This product is classified as state-restricted use in CT, NJ, for sale and use only by licensed applicators (your entire order will manually be canceled if you live in a listed state and add this product to the cart without a license number).
