I have an above ground 27' round pool. Last week we went on vacation and when we returned out pool was still crystal clear. There was a little bit of debree on the floor, but I vacuumed it and it still looked great. After vaccuuming, I put the chlorine tablet in the basket as usual and this is when the clouding started. All levels are fine except chlorine. It remains low. I have done 2 shock treatments in the last week to try to raise chlorine levels, but the levels quickly go back to 0. The water is cloudy and I am frustrated that shocking and clarifier isn't working.
Can someone please help? Thanks!
