No Bob, there is little or no waste in agglomeration, and the current flow starts of at 8mA and as the conductivity increases so does the current flow, and I have limited that to 40mA
If I had the time I could plot the whole scenario, until I retire I simply haven't the time to check it out with the running of my own business taking a huge chunk out of my day!! I would like to know what the signs are of a "large amount of silver wasted in agglomeration"?

If not then there probably is a large amount of silver wasted in agglomeration. "Ole Bob" ?????????. Sounds like you have developed a great system. One question I have is that initially you used 100ma at 8 hours to get 5 gallons of 25uS CS, later you used 40ma at 5.5 hours to get 5 gallons of 28us CS (about the same conduction reading, but the second condition is taking less time and current). What do you attribute that to? Perhaps Bob (or anyone else) can comment too.
