Disinfectants are not a good thing for a hot spring unless you want to treat them constantly like a swimming pool. The chlorine just kills some of the microorganisms while leaving the stronger (and perhaps nastier) ones alive. The complex ecology of the pools is altered and most likely not for the better.
