Grizz,
You can't go by what ionic silver does in a petri dish to determine it's effectiveness inside the body. Direct external application maybe, but there's evidence that ionic transforms within seconds after entering the body.
If you don't believe me, ask the man that sold you the Silvertron. He has very little faith in ionic silver as most of the research he goes by was done with colloidal. (Personally my experience is that ionic silver is great for anything in the body it can be directly applied to - but not once it enters the digestive tract).
And the kind of colloidal silver you get using a reducing agent results in protein colloidal silver that I spoke of where the particles are too big to be suspended in water. So gelatin, corn startch or other proteins are used as the medium for suspension. So not nearly as good as true water suspended colloidal silver.
There's a lot of info in all directions to wade through here but your information is not completely correct and I don't want others trying to figure it all out here to take it as gospel.
Even your belief that the lower the voltage the lower the ion size is not correct. Bill stated that with the troy ounce of silver in particular there was no difference in particle size or advantage in going less than 15 volts.
Not to be adversarial - just to say keep reading (and have a conversation with Bill). This takes ridiculous amounts of research to be an educated buyer because of all the disinformation from all sides.
