Have been working on algae problem on my 1/3 acre pond 5 to 6 ft deep, no fish. Copper Sulfate and Cutrine Plus as well as pond rake have really helped alot. Still have a few small area of algae and would like to add some color to water. Is it OK to use Aquashade and Cutrine Plus at the same time,mixing both in my 50 gal sprayer which will cover entire surface?
