    Help needed with cloudy water!

    I have had trouble with cloudy water since opening this year. At one point a few weeks ago the water was somewhat clear but not crystal clear like it should be. I left town for a few days with my solar cover on and came back to a green pool. After reading up I decided to Slam the pool. My CYA was 60 so I maintained a FC of 28-30 for several days. Within several hours the water was blue again but cloudy. I have seen some improvement in clarity of water to the the point I can see the bottom in the shallow end but not in the deep end. I have brushed and vacuumed daily. I have a dolphin robotic cleaner that has ran almost non stop since starting the slam process. I did the overnight test and saw no drop in FC. Still the clarity of the water is not good. I have a Hayward S-240 filter with 1 hp pump for a 38900 gal pool. Any help would be much appreciated.

    Sounds like you're on the right track. Sand just takes awhile, so keep the SLAM going until it's clear.
