Salifert as well, though the shading can be a little tough to tell small No3 changes.
I have heard good things about the Nyos nitrate test kit. Shading is said to be easier to tell. I have not used this on yet. Last time I tried at BRS, they were out of stock.
 
The Nitrate test by API is a blunt instrument. That being said, one can mistakenly switch the caps and contaminate the solution.

For you SPS guys, I can't imagine not having a Hannah.

Did Hanna start making a Marine Nitrate tester?
