I've been reading that some people are claiming that red welts come from 192aa not 191. However the more I research I find people complaining about the nasty red welts from people using everything from browns, kefei blues (which are giving them to me right now) Jins and Americans. The blues do seem to be giving welts to people more frequently however.

Has anyone tried an alternative to BA water such as regular sterile water? Would this be possible?

Or if it is impurities, there probably isnt shit one can do about it...

Is there a definitive answer to this question?... or simply just speculation?
