Yayyy! My first colloidal silver generator (photo)

Anyone tried using bottled Colloidal Silver? I found it at 500ppm. I have done the 9v battery deal along time ago but for simplicity would the bottled version watered down to 20-50ppm work?

For £23 you may as well just grab half a litre at the right strength.
