I have my pool almost clear, its still cloudy but I can see the bottom. I am running the DE filter 24 hours. I have filter socks. I just vacuumed an hour or so ago and I am seeing debris on the bottom. The pump runs at about 15 psi. If I back wash, it goes down to about 11 then right back up. I just swept it to get the debris off the bottom so the filter can get it. The chemicals are all good. Will this just take time to get clean or am I missing something?
