NO3 measurements. Tom, you are right. The La Motte kit will do 0.2 nitrogen,
I forgot to multiply by the ??? 4.4 factor. So I'm up to 0.8+ but have a long
way to go. No, I'm no longer using the Seachem Nitrogen. I wasn't sure I could
measure where I was going. You may be right about the M. praecox going belly up
for some reason other than NO3 addition, the females seem to outlive the males
by a bunch.

Thanks for the help,
Sharon
