Roger and Frank, I suggest that one measures the NO3 at the time of manufacture and then daily for several days. If the DW is very low in impurities then the anion will be ozone.
I have another batch that will be ready at 12:15 my time (CST). It is being made with a DW that has 3.2 uS/cc conductance. This is to verify NO3 change with conductivity. The ad for Silver 100 says it is complexed with citrates and potassium. so I am looking for something like potassium bicarbonate to provide the anion. We all need potassium, and it should bring up the pH to 6+. "Ole Bob"
