Abby from Clyde, Ohio writes

Do you need to dissolve the Crystal Blue Copper Sulfate in water and then spray on the pond, or can you just sprinkle the crystals in the water?


For most applications of Crystal Blue Copper Sulfate, you will dissolve the granules in water and then spray over the water surface. Per the product label, you should not apply granules directly to the water unless you have the proper equipment and are already familiar with this treatment.
