Ok, so I passed my overnight test, kept the FC levels at or above shock for more than 3 weeks now, backwash only when needed, checked for channeling, and my water is STILL cloudy. I've run the pump 24/7 now for about 6 weeks. Here are my numbers from this morning:
FC 13.5 on 8.25% bleach
What am I missing? I have added PuriFiber to the filter to help with the little stuff, but it stays milky.
