Almost sorry I started this...
Thank for the links. That's quite a bit of information, but I still haven't seen anything to tell me if the product I'm using (sold to treat boat and RV tank water) is affective at keeping keep bacteria from growing in the water I use on the boat to wash my hands and dishes. I am not interested in whether it should be ingested for health benefits, as a cure for baldness, or just for fun. But it hasn't turned my hands purple, or the water pink, and it seems to get the dishes clean, so I guess it's OK.P.S. I actually drink soda on the boat so there goes my teeth.
