Side note- my FIL's pool (usually his pride) was cloudy. I felt so bad, but we were only there a short time and no one would have been able to help SLAM (plus they were throwing in Algaecide). Either way it's in Ohio and they'll be paying someone to close it soon (since he can't anymore), so it wasn't worth the effort at this point. Just funny that in my head I was all "I can fix this with bleach, acid, and time" lol Plus they wanted people to be able to swim so couldn't really shock as much as necessary.
