This is how easy it is. Pour distilled water into a mason jar, screw the SG6 on to the jar, set the ppm knob to desired ppm, and flip the ON switch ON. Wait a few hours and you have Colloidal Silver . No Science degrees required. The silver puppy is even easier, nothing to set, just add water, flip it on, and it shuts off at about 15ppm which is as easy as you can get.
