My pool was cloudy. I did the SLAM process as recommended, ran the filter non-stop, and now it is crystal clear. Thanks to the people who explained it on this web site. I am curious about just what happened. The water was not green. It was a milky cloudiness. Once before the water got green and I slamed it and I understand that. SLAM was killing the algae. But what is the milky non green cloudiness? Is it indirectly the result of algae, or was it some other thing growing in the pool? If so what?
