So, I decided to do a SLAM since it seems like I have algae creeping back every time I think it's gone. Since the other day when I ran the auto cleaner to get rid of what I thought was dirt/pollen on the entire surface of the pool, my deep end is now green. I really thought I had this beat, but I guess not. Anyway, I've raised my FC up to my shock level of 24, and it's holding right now. Just for kicks, I checked the pH, and it was at least 8.2. Is that just because of the shock level? Or do I have a bigger problem?
