If I start with some eis already in the jar when I fill it with distilled water 
2-3 hours.  If I start with straight distilled then longer... maybe 5 or 6?  
Your equipment is so reliable I kind of set it and forget it for a bit and 
haven't kept track of times in quite awhile.  
The interesting thing, to me, is that when I dry off the rods now they leave no 
black residue on the paper towel.  They used to leave black marks.  Is there 
anything that needs to be done to them to remove the white patina (sort of) on 
them?
The Tyndall line used to be fine and tight and now it is wider and fuzzy.
Thanks.PT

 How long is it taking to run a 10 PPM batch?

Hi, Lately I've noticed that when I clean my rods with a paper towel nothing 
comes off of them.  Also no black speckles in the eis and no light yellow 
color.  Laser shows a wider line and can almost see speckles in the line... not 
the nice tight line I used to get from my silver puppy.
Any ideas how to get things back to normal?Thanks.PT
