 Awesome - thanks.  I'm looking forward to seeing your LEDs too (I'm half way through my build btw).  I'll shoot you a PM.
 
Thanks.  Great link.  That's the solution I've been using.

			Are you using a digital scale for DIY? I've found with a scale its dead nuts on, teaspoons and all that, not so much.
		
		
	 
 I don't have a digital scale.  I went back to the article today to mix up a new reference batch and found the disclaimers about the 2-liter bottle  sizes...hmmm, better to just do it with an off-the-shelf product if possible.  Bonus, I can then use the calibrated unit to confirm that my DIY mix is on target as well.
FYI...my refrac was calibrated with DIY last year.  I checked it today with the same solution and the solution is now reading 40 ppt.  Hmmm, so I pulled out my back up swing-arm hydrometers and neither of those came close to matching.
