Q:
Hi Utopia,
Which silver do you use to purify water, ionic or colloidal?

A:
Hi Pat,
Either one, but I prefer ionic in the event there are large amounts of minerals that might cause the silver particles to clump together and fall out.
Utopia Silver sells both particle and ionic kinds under the names Advanced Colloidal Silver and Advanced Ionic Silver.
