Recent studies which I read about somewhere on one of the Aquarium web sites
last fall (forgive me, I don't keep notes on all this stuff) could find no
traces of Nitrobacter or Nitrosomonas bacteria in established aquarium
biofilters. The experiments used some kind of dyes specifically designed for
locating and tagging these two bacteria. Neither of these two genera (this
is the right word) is involved in the nitrogen cycle long-term, although they
are what is packaged in resting state form in the commercial products.
Research continues as to specifically which nitrifying bacteria are at work.

They do work short-term, and allow the system time to establish the correct
bacteria before the Nitrobacter and Nitrosomonas die out.
I think you guys have missed or forgotten the nature of the original post.
It was about experimentation with high nitrite levels. Instead of debating
bacteria, I would like to know what ARTIFICIAL means was used in elevating
NO2 levels for the experiment.
