I am very interested in this thread...I don't know the best water to drink either!
As far as bacteria, I know many that boil all their water, when cooled place it in glass jars.
Claiming a lot of bad stuff evaporates away....what bad stuff evaporates?
Could placing a crystal change the properties? Which type of crystal?
Could putting a little apple cider vinegar in change anything?
I'll be reading, thanx, great topic, imo.
