I have a special problem that I need some expert opinion. I have an inground plaster pool with an overflow perimeter canal and a SWG , automatic ph regulator, sand filter to witch I add DE. This is my first winter. Every time after a heavy rain my pool becomes extremelly cloudy. I followed the SLAM procedure the first time three weeks ago and after working the pump 24/7 the pool cleared up after 4 days. Ever since my FC is 25 ,with CYA 55, ph 7.6 TA 80, CH 320, salt 3400 constanly ( SWG minimum dial -pump 24/7 and water temp 16 Celcius) for the last 3 weeks, but since we get a lot of rain here in southwestern greece the pool got very cloudy again. I suspect that all the rain water from the concrete around the pool (along with a lot of dirt apparently) gets in the overflow canal and consequently in the pool. Could I shutt off the overflow operation and just recirculate the pool water? Is it normal for a pool to be this cloudy after 2 weeks of heavy rain? Remember I run the pump 24/7 and have FC way above shock level for my CYA the entrire time. Thanks for any help..
