I wonder if without bioballs, the crud must therefore be deposited on the live rock, sand, etc, closest to the denitrifying factory. Bioballs oxygenize the water so well, that the nitrates developing in the crud have no chance of being denitrified, once it's stuck there.

I've got a sheet of filter material positioned just below the flow into the sump, to catch any matter that it can. I change it out or rinse it well every other day or so.
