I will backwash again today and have vacumed the bottom a couple times as I know there is stuff on the bottom even tho I can't see it. I think now that the chlorine is'nt burning off within a couple days it should be clear. I opened it sunday afternoon and today is the first day that I have been able to keep chlorine in it 24 hrs. that should make a big difference. I was in a hardware store today and saw 10% chorine for 2.25 a bottle, I am going to go and get some. This afternoon the pool is really blue( yet milky), how high should I take the chlorine level up for tonight and tomorrow? It was 85 and sunny today and is supposed to be the same tomorrow.
