About 10 days ago, our in-ground 16K gal pool turned VERY cloudy. Testing showed no abnormal chemicals except high cloriine level. Weather in AZ has been hot, dry and VERY windy, so I figured it was just the in-floor cleaning getting overwhelmed. Lowered the SWG setting to 15%, changed the cartridge filter and started running the pump 24/7. No improvement - actually got more cloudy. Last weekend we went the Borax route, and still no improvement. One thing that surprised me is the chlorine level still very high, so I measured the salt concentration - 7200ppm!!! Very strange (although it does explain the high clorine level with low SWG setting), especially since the SWG sensor is reading 2300. Here's my chemical readings. Have been trying to avoid using a clarifyier, but am desparate. Any suggestions besides drain the pool?
