I had someone ask me for the "ppm" number if I run the Silver Puppy way
into overtime like 12 hours or so.  I know that almost all people are
reading the ppm number off a tds meter that's calibrated for table salt,
getting people to understand calibration is a losing battle.

I just picked up a batch that's been sitting around for a while and it
reads 14 uSeimens, so for that batch what should I tell them? 

Or do I just do like the eBay marketers and make up a number?  "It's
42000 ppm, it's REALLY good stuff!"  :)
