really? That is surprising to me. Somewhere around here I have a PPM meter. I guess I should take it up.
I don't the water from the jar, cleaned off the silver leaves, and put in more water. I plugged the unit in and put it into the water. On the "auto" setting the light does not come on, however on the "manual" setting the light does come on! What gives?
Also, on my other unit you could tell it was working because bubbles would form around one of the leads. Does that happen with this unit also?
