Yesterday I was wondering what the difference is between getting out of a pool with only an appropriate level of FC and no CYA and a pool with both FC and CYA.
I'm trying to figure out if failing to rinse off in the shower after swimming in a pool with FC: 9 and CYA: 80 is better or worse than failing to rinse after swimming in a pool with FC: 2, CYA: 0
I can think of a few things going on here, drying, oxidizing and higher UV exposure due to 0 water depth.
What effect would this have on your skin as the water dries? I wonder if the equilibrium begins to quickly break down causing the CYA to rapidly release the bound chlorine? It also seems likely that there is more to oxidize on the surface of your skin than in a volume of water which would also cause the CYA to release it's stores.
Just something to ponder....
