Safe swimming with elevated chlorine

[cheshamjim]

Someone posted this on another thread recently. Seems like a really good article on the relationship of CYA and chlorine. It explains ORP (oxidation reduction potential) and references academic studies on this subject.

I was curious earlier whether the bad effects of high chlorine were somehow reduced in a high CYA pool, so I started a thread on the subject.

I am a believer in Ben's Best Guess chart and dose my pool accordingly, but I also appreciate the questioning of fcfrey. It contributes and keeps us honest.

edit: ...and prompts a pretty good post from PoolDoc.
