I've been helping my cousin out with his pool on his new house which was a foreclosure. The pool had been neglected for 2 years and looked like a swamp. I had him by a Taylor K2006C kit and have been at his house several days over the last week to try and correct his problem. After adding some liquid chlorine, stabilizer, borax, and running his filter 24x7 here are his current numbers after 5 days:
FC: 24-27 (shock level)
TC: 0-0.5 now
This is an above ground pool, 12000 gallons, sand filter, and 2 speed pump. Algae appears to be gone - followed Pool School's instructions, but the water is still very noticeably cloudy. You can sort of see the bottom. Was thinking of adding some Polyquat 60 but just not sure at this point. Should we continue shocking and running filter until it clears, or is something else up since there no longer appears to be any overnight chlorine loss?
