Vjeff; pardon me if I've overlooked it, but it appears you are still flying blind, and have neither an HTH 6-way or a Taylor kit. We can try things, but we're just shooting in the dark, without reliable water chemistry information.

You can buy and add a floc if you like -- I'm not going to recommend one -- some work sometimes; some work other times; none work all the time.

Since your cloudiness didn't settle, there's nothing to be gained by leaving the pump off. Given that you have an AG pools the odds are that you have an oversized pump and an undersized sand filter -- that's is what is usually installed, for marketing reasons. Worse, that combo tends to blow sand out of the filter every time you backwash, so if your filter has been in service more than a month or two, odds are it's missing a lot of its sand.

Good luck!
