Guest guest Posted January 27, 2010 Report Share Posted January 27, 2010 Bruce is making it at about 12 ppm. He says that anything less than 10 ppm won't effect problems like cancer. If you try to make it over 15 ppm it clumps up into too big a cluster and won't penetrate cells. Commercial stuff made at 50 ppm and diluted isn't good. AC seems better. It makes particles that aren't charged and repelled. It makes smaller clumps too. I'll be interested in results if you're going to study CS. > > The 2500v CS had what ppm? bob Quote Link to comment Share on other sites More sharing options...
