Re: TDS-1 What it actually does!
This sounds more like an answer to my original question a week or so ago. I thought it would only measure ionic silver and not include non-ionic silver. Thanks for clarifying.

Should be okay to check the quality of water before the process begins though. As a side thought, has anyone tested their water before and after ozoning it? Just curious. bjs -- The silver-list is a moderated forum for discussion of colloidal silver.
