Cloudy Water & CL Going Going Gone

[KurtV]

I think you've gotten sound advice from Marie (mbar) and Dave (duraliegh) on shocking your water because of the high overnight chlorine consumption you're experiencing, but I wouldn't overlook the cal-hypo as the possible cause of your cloudy water. Cal-hypo can cause cloudy water temporarily and because you've been adding it regularly, it could well be the culprit here (for the cloudy water only, not for the chlorine consumption). Try bleach as your chlorine source instead and see if the cloudiness problem is ameliorated or eliminated.
