Copper Sulfate Crystals Algaecide
Crystal Blue Copper Sulfate is a great pond algae control product for filamentous or string algae. Â Copper sulfate should be used as a pond algae treatment on actively growing algae in water temperature above 60F. Â 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. Â Copper sulfate is safe for most varieties of fish (see restrictions below) when used properly. Â Granular copper can be applied in one of three different ways: broadcast crystals, place crystals in a burlap bag and drag behind boat, or dissolve crystals and spray. Â The application method we recommend is to dissolve the crystals in hot water and spray actively growing algae.
