2 fluodized bed theory

[telecubby]

The theory is running two very efficient fluodized beds in series ,so the 1st nitrify's very efficiently stripping the water of oxygen with areobic bacteria then haveing that bed feed directly into a second bed to see if denitrification occurs in the second fluodized bed.
Any comments or reasons why this surely would not work?

I admit that I'm no microbiologist, but I don't think you can ensure that all of the oxygen is used by the nitrifying bacteria in the first filter. If the consumption of oxygen is part of, and proportional to, the nitrification process, it will be dependent on the amount of ammonia and nitrites in the water.

Like several other theories from the same source, not worth the wasted badwidth.

whenever you don't have anything witty to say you say something hateful RTR. Fluodized beds already being ,some say too efficient becomeing nitrite factorys do almost too much @ the front end of the cycle so a fluodized bed filter rated for a 400g tank would or should pollish off all the oxygen b4 entering the second I was thinking & in fact would have to as their is no way to seperate chambers in a fluodized bed ,its all active & in rotation .The only real succes ive had is in an airtight large round vessel under slight neg or pos pressure but was a little prown to drip leeking from the slight presure(unfluodized mind you).
