In context, Bob was generalizing that by the time you get much over 15ppm the current will be so high that it is producing undesireably large particles. The smaller particles are still there, but you're wasting time and energy going for "ppm" that won't be used. With our typical low voltage generator and no salt, you'll start out at a trickle of current and build up to many tens of milliamps by the time you get to 20 or 30 or more ppm. Bob's contention, which I can agree with, is that the longer you let it go and the higher the current, the bigger and less useful the particles get. I've been making stuff in the 20-25 ppm range. When sometimes I've forgotten to turn it off on time I've generated higher ppm batches. These, interestingly enough, tend to "lose" ppm over the days and weeks, moreso than the batches that were run for shorter duration. The indication here is that towards the end of processing, I'm really not generating the small, charged particles that I want to be. Some folks suggest making no more than a few ppm and just taking a lot more. I can agree with this. I certainly plan to explore and document it for the web site. Advantages: simplicity; less time to produce; less sludge on the cathode; uniformly small(er?) particles. Disadvantages? Higher ppm might work better for topical use? Great discussion, folks! Mike D.
