Hi All...

Just to few points on Nitrogen fixation.  This process is a very " expensive" process for bacteria 
to carry out and they will only do it under conditions of ZERO nitorgen and ZERO oxygen.  O2 will 
destroy enzymes needed for N fixation to occur.  I can't think of ANYONE who would have these 
conditions in their tanks!.  On the productions of CN...it is impossible because CN is a electron 
transport decoupler and it would destroy the bacteria's ability to photosynthesis as well as 
respire and fix N.  So this is proabably not an issue.
