If the FC is in acceptable range, what causes the pool to go slightly cloudy after several people (or many) are swimming for awhile? Seven of us swam tonight and I thought I noticed a slight touch of cloudiness at the very end, whereas the pool had started crystal clear.
I tested when we were done and FC is at 8.5 (still coming down from my impromptu shock due to paranoia) and CC was 0. (CYA was added to target 80 a couple of days ago, but I haven't checked it yet.) If there is indeed some cloudiness from our time in the pool, do I do anything about it? Will it take care of itself if our FC is in range? I am running the pump overnight because I'm trying out a fountain we made in an attempt to drop the water temperature, but would I want to filter all night even without the fountain running?
I'm also asking because we are having a pool party on Sunday and I want to be prepared for the high bather load. I know to bump the FC up beforehand with bleach, and afterwards too, but I'm curious as to the causes of cloudiness forming while swimming (whether or not my pool actually got slightly cloudy tonight, which might be my continuing paranoia )
Thanks in advance for enlightening me!
