I just don't see the mechanism.
I agree with you. It's not the amount of bleach used so much as the maintained level I was originally thinking of reducing. Right now and forever I'm going to have to keep my FC level at the higher end (relative to CYA) to keep the algae at bay. That's ok by me. I just wanted to explore other options. This thread is proof positive of the BBB method works best.
