Some of the high volt (and even low volt as of late) generators can make a cs without tyndall. There are some on the list that swear by it. Theory being smaller particles will be able to get into cells and kill virus bugs, etc.. What seems to be needed to produce small particle cs is to have a very low current density, which your last experiment seems to have.
Most people get in a rush and try to put more current through to get a higher ppm. IMHO, ppm is not a good measure of how effective cs is in bug fighting, but we don't have an agreed upon alternative way to rate cs (that I know of). Heck, it will probably start a war on the list to suggest that ppm is really a bad way to rate effectiveness, we only recently got 'most' on the list to understand the a tds meter cannot tell the ppm of cs. Yes, different generators make different sized particles. That is why I think ppm is a terribly misleading thing. A dime in the bottom of a glass is a very high ppm, but won't cure much. Etc., etc.. Sorry to get off subject. I have both the 10k volt ac setup and a current limiting dc setup with polarity switching 0-35 volts. The dc setup has become my favorite as it is so very controllable. I can shut down at a given voltage draw and can keep my cs with as little or as much tyndall as I like. Current limiting is the greatest. Keep up the good work.
