What is the maximum chlorine level you could have and still be safe to swim?
Thanks

Asking that is like asking how high is high. Everyone has an different opinion.

I use 10ppm as a guide line. If the level was 11ppm and a hot day, I would still let the grandkids go in. I would just tell my wife to make them take a shower when they were done swimming. To know when enough is enough, I would watch their eyes for redness.

I hope this gives you alittle help.

It all depends on your CYA level. Higher CYA levels allow higher FC levels.

I will swim up to shock level for my CYA level. Some people are willing to go higher.

I think I've jumped in at 13ppm, CYA was 100. I made sure to wash suits immediately, as well as myself!

Another way to look at it: have you ever jumped into a pond? That had no chlorination, and most likely quite a few yuck molecules swimming around with you.
