I received my test kit a couple weeks ago and have worked on lowering my CYA to 60. On July 1st I started slamming our pool. It looks blue now but still very cloudy. When I tested it at 1:00 my readings were:
FC 23.5 added 16oz. Chlorine
PH 7.4 (on 1st)
So, I'm now in my 9th day of slamming. How often should I clean my filter? Any advice or help would be greatly appreciated!
