dont understand why some people get sediment in their silver. when I make it its Crystal C., no sediment etc., dont run throught coffee fileters etc. my tyndall effect is super fine: my hanna meter reads 5PPM thats all I take. so its perfect. never had a problem. I use pathmark distilled water, air bubbler, and HVAC into my .99999 silver rods. after appox 1hr I have 5PPM.. I usually check the distilled water with my hanna meter before I make it. make sure its .000
