Dk, welcome to the forum -
I looked at your posts from last year and noticed that you converted from Baq and had sand going back into the pool. Did you change the sand? I'm wondering if the sand in your filter is ok or if there's something (residual Baq) in the sand that is keeping the water from clearing up. That's just a quick idea that popped into my head after revewing your old posts.

Janet is, of course, right about the other possibilities and the need for as much info as you can give on the pool, without the info, we're just making guesses.
