Thanks alot for the replies. The only thing i am curious about now is how to make the higher ppm Colloidal Silver . In the manual I got from sota it says "the finest quality Ionic Colloidal Silver at a rate of 5-8 ppm (part per million) in 2 Hours for 16 ounces of distilled water" If I was do try upping the ppm how would i go about it? just leave the silver generator on for longer? if so how long for a pint or CS?
