[APD] NO3 Management

[Phil Bunch <pbunch at cox_net>]

I took note of the suggestion to use an out-of-tank hydroponic filter as 
one means of removing NO3 from aquarium water. Has anyone one designed an 
out-of-tank anaerobic system for nitrogen removal? I can see some problems 
that would have to be overcome but it sounds possible. Possibly a 
deoxengenator on the input and return through an air reactor?

Just a thought.
