I’ve been reading through all the articles here and I’m very excited to begin my first ‘real’ colloidal silver setup. I plan on starting out with 20ppm however eventually would like to try making the higher concentrations. I could have sworn there was an article or a post somewhere here specifically about making higher concentrations however after spending the last 2 hrs sifting to find this article/post I have failed to locate it. Can someone help me find that post? Or can someone simply lay it out for me how higher concentrations are yielded? Thank you!
