Then you more than likely have an ionic silver 75 to 85% with a 15% Colloidal Silver . Had to know since TDS meters only give a "ballpark figure of ionic" and don't read CS at all. Knowing your current flow & time of brew and volume of distilled water plugging these numbers into the faraday equation to give your PPM's. There are several sites on the web that have pictures of various color of CS and you could try to match these up to what you have to get a "ballpark" of your PPM of CS. Worth a try so you have some idea of what you are using. I have used from 5PPM to 30PPM and have had good results. Using a light bulb thats transfering heat into the solution will give some reduction of the IS to CS.
