Ash said:Noman's TEK says use distilled water. Is this important and why so? SWIM uses tap water, and can't think of a reason why this is not sufficient compared to distilled water.
Ask your local water board for a list of the metals and contaminants left in your supply after treatment...you will probably never drink it raw again...:surprised
As for xtractions...its just cleaner and less chance of a 'reaction' from contaminants...
