Sorry, I can't convince you not to fill in your pool because we filled in ours! We've never been able to figure out what Hurricane Ida blew into the pool but after having pros work on it, analyze and reanalyze the water for months, my husband asked me if I would mind if he filled it in- I just told him to do what he felt was best so he rented some kind of machine that beat up the concrete and a backhoe(?) to fill it with dirt. On the upside, I think he had a really good time, lol.
