Ivan, "Ole Bob" and others, Thanks for your reply.
I just have completed a DW (distilled water) test this afternoon using a bubbler only. I used approx. 16 oz. of DW and I set it up exactly as normal except no power applied during that period. (I did not apply the 30V dc that I normally use). I do not use a stone to distribute the air. I have tried a couple of them fefore and it did not work well. Instead, I use a plastic tubing with one of the ends blocked and I connect the small "jet stream 600" motor output at the other end of the tubing. Only three small needle holes (to distribute the air) used on the tubing that fits between the two electrodes (at the bottom end of the container). I ran the bubbler for two hours with a reading of u/S taken every 15 minutes. My DW at the start was 1.9 and it finished at 3.9 u/S. It went up from 1.7 to 2.6 in the first 15 minutes... At the end of the first 1/2 hour it was 3.2 and stayed around there till the end with a 3.9. I suspect that my container was not 100% clean at the beginning and it might be the reason why it went up that high during the first half hour. On the overall, it does not appear to change that much, unless the effect is different when the voltage is applied, but I do not beleive that it would be worst.
