Why won't you try the simple test I requested? I'm not holding my breath about you doing it since it would probably impact your earning potential.
As for results of water ananylsis, its been done already, by a manufacturer, who thankfully was honest enough to admit there were only ferrous compounds consistent with electrode corrision, consistent with the electrolysis process they use in their machine. I've already posted their results, but you seem to know even more than the manufacturer so take up the issue with them!
