## I've been wondering if the silver ion is only produced on the positive cycle. And why is one electrode submerged and the other not? [Or does this question apply to a different HVAC device?] I forget, do you use current limitation? In addition, BRAVO! Marshall. Sounds darned good. So now I wander why my Silver Genie produces sludge so effectively. I guess HVDC with sumerged electrodes does not react the hydrogen and oxygen. [gotta take that thing and put it on the oscilliscope..it just says high voltage, not AC or DC]
Appologies for being such an enthusiastic verbose newbie on the list..I'll wear down eventually. If questions go unanswered, no problem. I'll go elsewhere for them.
