Can you have the best of both worlds? I have had bad luck with algae. Tried amurs, some luck, not much, copper sulfate, one pound per acre, not much luck and for a short time. Cutrine granular, some help, not much. Now the real problem. My wife is mad. I killed all of her beautiful hearty lillies. someone told me to use Princep which is the same as aquazine to control algae. It worked great. Lillies and all. I also added aquashade at the same time. I put 10 lbs of Princep in my 1 1/2 acre pond. It seemed to kill everything green. We would like a semi clean pond and water lillies. Is this possible?
