Hi there! I just shocked my pool, and I was wondering how low I have to let the chlorine level to drop before I can let people back in the pool. Using the pool calculator, my Cya is at 45 which puts my ideal chlorine range between 4-8. The shock level for the pool is 16. I told my wife and kid that we have to wait until the chlorine gets down to 8 which could take 3-4 days at the rate we loose chlorine. We have some hot days coming up, so I was just curious if I could let them in any sooner?
