Crystal Blue Copper Sulfate Smart Crystal 5 lb*Crystal Blue Copper Sulfate Pond Algae Control is a great pond algae control product for filamentous or string algae.  Copper Sulfate Pond Algae Control should be used as a pond algae treatment on actively growing algae in water temperatures above 60F.  When getting rid of algae in a pond, it is always important to treat 1/2 of the pond algae at a time to avoid killing too much algae and depleting the water of oxygen.  Copper Sulfate Pond Algae Control is safe for most varieties of fish (see restrictions below) when used properly.  Granular Copper Sulfate Pond Algae Control can be applied in one of three different ways: broadcast crystals, place crystals in a burlap bag and drag them behind the boat, or dissolve crystals and spray.  The application method we recommend is to dissolve the crystals in hot water and spray actively growing algae.
