I make true Colloidal Silver using high voltage, and it is tasteless, and colorless. most people dont know how to make high voltage AC Colloidal Silver , so they push what they know DC battery types. let me know, I can help you and show you how to make high voltage AC. the results are fantastic. I personaly use .99999 thats 5 nine silver rods. the purest silver on earth. and I just go to 7PPM the 7 is the magic number. but still nano size particles. .001-.009
