this article overall seems good
http://www.poolspa.com/publications/sin ... ocktrt.htm
However they have a paragraph which says this:
<<If too much chlorine is added, it may take days to drop to safe levels (less than 5 ppm) before bathing can be resumed.>>
Based on the CYA/chlorine chart here, my target chlorine is around 6. People here have posted that up to shock levels of chlorine are safe.
so which is it?
