I have started running my pump and filter for a few days now before taking cover off and before I started the pool was crystal clear now it is cloudy. I went cloudy about midseason last year & I couldn't clear it up and now I have am confussed as to why!! Could the filter valve assembly be bad? I replaced a seal last year because it was leaking from valve but now I am thinking that maybe the valve may be no good is there anyway of testing or checking if it is the valve or not? Any suggestions would be appreciated. Thanks in advance.
