I can see the bottom of the pool, but it is not as clear as it was last year. It has had this slightly cloudy look since I opened it. I've shocked a few times.
FC Levels have been holding well, so it's not like there is algae in there burning it up. Swimmer load is light.
My wife is threatening to take a water sample to the pool store, so obviously, this slight cloudiness is a really big problem! ;)
