Product Q&A

Answer:

For most applications of Crystal Blue Copper Sulfate, you will dissolve the granules in water and then spray over the water surface with a hand held pump sprayer. 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. Crystal Blue Copper Sulfate should be applied on a sunny day after mixed with water. You should spray one-half of the water area and wait 14 days before treating the remaining half. This will prevent the suffocation of the fish.
