Have a 14,000 gallon in ground pool, plaster, filter cartridge, 1/2 HP pump, kreepy krawly with leaf trap, Chlorine puck floater.
Had no problems until 1 month ago when our water kept looking cloudy. Used concentrated clarifier several times, no improvement. Replaced the filter cartridge because pressure had doubled from baseline. We went to have the water tested at pool store, could not read because Chloride level was too high. Waited another week with no chlorine tabs, still too high. Pumped 1/2 the water out and refilled. Retested at the pool store, everything looks normal and chlorine level has come down.
The pool still looks cloudy! We added natural clarifier, which we were told could not be overdosed. No change.
Is there a doctor in the house?
