Ok, so last year I had the same cloudy issue. The pool is about 20 by 40ft inground. There are two skimmers and a main drain, and two outputs. One output in the shallow end, one in the deep end. I have balanced the pool by getting it tested once a week and using the necessary ingredients. I have shocked the snot out of it a few times, when doing so, I put in about 4lbs of shock. After shocking it, I get it tested again a few days later. My pool gets better in the shallow end, where i can see the bottom, but not crystal clear. The deep end remains cloudy, to the point where I can't see anywhere near the bottom. I have used clarifiers, the balls for the skimmer, tablets...everything.
I think it would be neat to have one of those pools where you can see the bottom. You know, like the rest of the world has.
Please, I welcome your thoughts.
