I have a sliver puppy and I make silver for other people quite often yet when 
they ask me I cannot tell them what PPM it is. 
 
I have heard that it depends on the quality of your distilled water.
 
Is not distilled water distilled water? 
 
How do i know what is good distilled water and what is not?
Does distilled water have a shelf life?
 
In general what ppm range can I expect.
 
Also, I store the CS in bottles identical to those brown hydrogen peroxide 
bottles. Is that OK and what is the shelf life of colloidal silver?
 
Thanks
