First time opening my pool. I'm just starting to add CYA with a sock in fron tof my return line and had two quick questions. First, is it safe to swim while CYA is being added as long as I tell everyone to stay away from the sock? Second, my pool installer added quite a bit of bleach when they were adding water so right now my FC level is between 5 and 7 (with no CYA), safe to swim at this level? I know it will burn off today since it is super sunny, but of course everyoen wants to use the pool now!
Thanks for your responses.
