Frank: My process is quite similar to Ole Bobs. So what I've observed during 
the production of HVAC CS should be relevant to your earlier suggestions. I 
run my process until the conductivity of the water gets so high that the 
combined ionized air resistance plus that of the water is too low for my 
power supply to continue operating at its 30 ma internal set point. So 
basically the product I get **already represents** the maximum total silver 
obtainable. However, the silver concentration is limited by conductivity 
constraints, not ionic silver precipitation. In fact, if I were to change the 
physical configuration of my setup, I don't see any reason why I couldn't 
continue producing CS. However, I'd need a longer tank which I don't have.
