Hi all,
I know @_Maq_ agrees with this and we both think, that in some ways, we are back to <"re-arranging the deck chairs on the Titanic">, because <"oxygen is the parameter that matters"> and <"everything else is just froth">.
Personally I don't care <"where, or by what">, the assimilation of ammonia (NH3) and nitrite (NO2-) occurs, I just want a system with the capability to deal with <"unexpected large bioloads"> and no single point of failure.

What we can do - and I actually did - is to compare two identical tanks with and without filters with bio-media. I've learned that it made no difference whatsoever. It suggests that substrate is quite sufficient and there's no need to build a separate room for bacteria.
Filter media is where most of your good bacteria are, substrate second most.
That is it, we just don't know <"Is expensive bio media worth it?">. We can, however, make some <"educated guesses"> based upon the scientific literature : <"https://www.sciencedirect.com/science/article/abs/pii/S0048969722029680">.At the very least, we should admit that we simply don't know.
