Hi Dave Edwards
So who is disagreeing? What you say is all good stuff. Lets hear more from
you about the method you use and any failings you encountered and how you
corrected them. I hope we are all here to help others  Some of the
literature you refer to also sounds interesting.  Would you  list this
data?  Can I suggest author first, year, name of publication then publisher
detail.
Re your comment that MLM add this and that I agree but not for the reason
you suggest.  The reason is to maximise an assumed value. Good colloidal
silver doesn't need anything really.
We are all born with a silver content!  It is the maintenance of that part
of our make-up that you are administering.  
regards,
Robert Beasley
