Deirdre Layne says that "the sonication process can destabilize Colloidal Silver " does anyone know how true this is?
I am using Steve Berwick's SilverEdge generator to make a 10ppm colloidal with a Aennon Cool Mist Humidifier as a nebuliser. I have noticed if you run the same solution a number of times visible partials form on the bottom of the unit does this mean the solution has destabilized?
Does anyone else run there solution several times or replace every time?
Any thoughts and is Steve still on this forum?
