Hi . We bought an above ground pool in May of last year . My wife was sold by the shister pool place that Pristine Blue was like the second coming of Christ. Told us it's easier and cheaper to maintain its clearer and safer fir our kids and grandkids to swim in . Well it was very clear after I finally got the chemicals balanced but it never totally seemed clean. Then we started having to buy every chemical they sold when we tested it every week . This was off that was off it was getting ridiculous. Now I'm reading that it's not that safe. Some countries have banned it I read . So we are wanting to switch over to chlorine. The pool had been shut off last October and was totally leaf infested and green. I've been putting bleach in and clarifier to and got out a lot of leaves but it's still cloudy . I ordered a new paper filter as the crappy one that come with it just blows all the green gross water back into my pool with out filtering it. What should I do next. The ph alk and all else check out ok on the stores test . What's my next move ??
