Thanks for posting the pic, PoolDoc. All the bleach is working. I've been adding 2 gallons of generic 6% bleach in the morning and again once the sun goes down...so 4 a day. Three days and the improvement is remarkable. Water is clear, but not 100% yet. I backwash the filter twice a day and it's gone from completely green to almost nothing there. My issue now is getting the dead algae off the bottom. I vacuum, but it's stubborn. I've tried with the automatic (lil shark) and manual vac, but it's not working. Any suggestions? I'm going to continue with the bleach, scrubbing and backwashng.
