Robert from St. Louis Mo writes

What is the best way to apply Crystal Blue Copper Sulfate on algae?

Answer:

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.
