My pool was uncovered all winter and we started getting it ready about a week ago. I think I need serious help because I think I have done any and everything to get it ready. The water is so cloudy We have above ground, sand filter. We had serious green algae, but now see nothing in our water at all. We have shocked and chlorinated about a million times. Also used algae treatment, changed sand in filter, swept and brushed everyday for hours. Our chlorine reading was still VERY low. We then resorted to Clorox. We poured 10 gallons in the pool. From the window the pool looks great, blue and no debris. But when you get close it is so milky, the bottom is not visible. Oh yeah, now our chlorine is testing extremely high, still cloudy! Please help, we really want to swim.
