Most if not all silver water sold in the marketplace is Ionic Silver and is not Colloidal Silver. Over time, the terms “Ionic” and “Colloidal” have been misused and confused. Ionic Silver (water clear) and Colloidal Silver (yellow) are in fact two totally different products with different properties.
