That is probably normal Melly, you are brewing EIS like most of us i.e. approximately 80% ionic and 20% colloidal. The concentration probably depends on how long it was brewing for. Mine normally reads 7 after the auto Silverpuppy shuts off. It will then go down to about 5 after a couple of days. This would mean it is around 10ppm. dee

How do i know if what i brewed is EIS or CS or combination of both or if it even contains silver? Yesterday, i brewed and my TDS read 7ppm. Today, i measured again by TDS and it is only 4. Is it normal to go down? When does it stop going down?
Thanks
