Tetra kits I have issues with as there vials are rectangular and there's
about 4 different viewing angles each resulting in a different color
readings!!!! they fail to answer my emails and I just droped there line
for my usage.  The nitrate kit that I currently use is aquarium pharm.  It
seems to be fairly sensitive and a somewhat narrow scale between results.

Hach is good but tends to be a bit pricy, however if you are looking for a
quality lifetime lab grade test kit then go with lamotte (www.lamotte) you
can order directly from them.  Also check www.mopetshop.com as they carry
some of the same kits at cheaper rates.  With the lamotte kit the refills
are alot cheaper than the initial investments are.

I've never used the dupla test kit.
