No, lol, good one though. I guess you're following things there. It was actually to use a particular soap. Purex ultra concentrate. It maskes the smell of SH better than anything ive used, but doesnt cling hardly at all. We used 40gl on just the side of the house and a small part of the back. I got on the roof at that point and noticed that the chems were actually rolling off of the algae without affecting it at all. I went to the store picked up some Dawn, and BOOM! Finished the rest up in about 2 1/2 hours, including touching up everything we sprayed at the beginning.
