Hi! I have been reading the list emails---thanks to all! for the good 
info.
I have been making CS only a short time with a  system that uses 3
9-volt batteries and two ,999 fine coins. I use  a  quart of distilled water 
heated to almost boiling;  process  30 minutes cleaning the coins every 10 
minutes. The product I get is pale yellow  then but by the next day is much 
darker.  Also there is a 
small amount of blackish sediment at the bottom by the third day.
I say a small --like a pencilled line with no visible depth.

Is  it ok to pour off the clear yellow Cs and  discard the sediment?
What about the PPM on this---
Love to hear your thoughts.
