Over the winter we never managed to close our pool and of course it got really green and full of leaves. We shocked it and put liquid chlorine in it trying to clear it up and it only changed the shades of green and made it incredibly cloudy. Instead of wasting money we drained our pool to about 2 inches of water (bottom drain would not drain anymore) and got all of the leaves out and skimmed it as much as I could. We filled it up to about a foot and drained it again to try to get any remaining algae out. Now we have refilled it and I have not put any chemicals in it except for the floating chlorine dispenser and we have little white particles that are not getting filtered out floating all throughout the pool making it cloudy still. I just replaced the cartridge filter and the pool is a 16 x 48 frame pool that holds about 5,145 gallons. I don't know the size of my filter though. I tested my water and my Chlorine is normal and my PH is a little high. Would adding PH reducer get rid of the cloudy or do I need something else?
