I must add to what I said in my previous post. I would not go into the water if the CC > 0 (> 0.5 or so) OR if you are still losing a lot of chlorine overnight. Having a high FC with CYA may not be a problem, but if the CC > 0 or you are losing chlorine overnight then this means there is still a lot of stuff getting killed or oxidized in the pool and you don't want to get exposed to that stuff if you can help it.
