I removed the solar cover to discover green algae growing in the pool. Brushed pool and brought CL up to about 18 (CYA is 50) at 9:00 this AM. Now the pool is now cloudy blue. If tomorrow AM the cc is 0 and pool holds chlorine level, can I start to let chlorine fall or do I keep shocking until pool is no longer cloudy? Does high level of chlorine cause pool to be cloudy or is it dead algae and the filter will clear it up?.
I cannot believe after the summer I have had with this pool I let this happen!! When I tested the pool this morning CL was 4 and cc was .5
Oh yea, we bought a new filter about 1 week ago and the cloudy pool I have had all summer cleared to crystal in 1 day. We now have a 150 lb filter to go with our 1 1/2 hp pump. The old filter was just recirculating water all summer. The new filter is great.

Thanks for all your help this summer.
