Mile from Tama, Ia writes
According to the product label, There are several methods by which to apply Crystal Blue Copper Sulfate to impounded water. Probably the simplest and most satisfactory method is to dissolve the product in water and spray the solution over the body of the water. A small pump mounted in a boat can easily be used for this purpose. Another method is to broadcast the Copper sulfate granules directly on the water surface from a properly equipped boat. A specially equipped air blower can be used to discharge the product at a specific rate over the surface of the water. Please refer back to the product label for more specific application instructions.
