Re: 2 Questions for the experts here

You are better of buying GoldenGevity's Collloidal Silver and dilute downward:

2000 PPM can make 200 bottles of 10 PPM
4000 PPM can make 400 bottles of 10 PPM
8000 PPM can make 800 bottles of 10 PPM
10,000 2000 can make 1000 bottles of 10 PPM
12,000 PPM 12000 PPM can make 12,00 bottles of 10 PPM

I would never make such LOw PPM because it is ineffective, however with 500 PPM of GoldenGevities Colloidal Silver , I have seen great results.

Understand how much 500 PPM Silver you can make just take the value (for example) 12,000 PPM, you divide 12,000 by 500 and that gives Tweet
