As I stated, I didn't lose FC over night, didn't see any algae, but I never really did, just the water wasn't clear. Water was clear.
I was going to maintain a 10 FC... you said crank the SWCG if kids were going to swim so I did that in anticipation that all the dirty little teenagers would eat up some chlorine.
It dropped to 12, I left it on boost/max because I didn't want my chlorine to drop below 10. If I came home and it was still at 12 then I would have felt like I was good.
But dropping from 12 to 9 while running a "20,000 gallon" SWCG on full in an 11,000 gallon pool makes me feel like I'm back sliding.
