I am by no means an expert, but after reading the thread I have a few questions. Today your alkalinity is 250. On 6/16 you reported 133. That is a big difference.

When you vacuum are you vacuuming to Waste or into the filter? If you are going into the filter, you need to backwash or the dead algae will get back into your pool making it cloudy. Every time you vacuum, I would vacuum to waste and get rid of that nasty stuff. Keep at it with the bleach.

Sometimes when lots of chemicals have been added it can make your pool cloudy. One time Ben talked about pool water just getting worn out and needing to replace most of it. There is really no time table or chart about it, but the theory is at somepoint, a person's pool water may not respond anymore.

Good luck and keep working at it.
