Water changes are fastest way to remove /dilute that which results in elevated nitrates assuming the tank isn't over stocked,over fed,or under filtered.
About anything placed in the filter will house bacterial colony, some material is simply better by having more surface area ,or by their pourus nature as opposed to smooth surface.
I think most of the bio media offered is more out of a concern for the material not to become compacted and to allow water to flow in less restricted manner = less chance for anerobic conditions which could occur. Just my two cents.
I think you're on the right track - periodic thorough cleaning rejuvenates bio-ceramic media by getting all the 'shmutz' out of there. Prolly only needs to be done twice a year at most by partially rotating media out, but worth the effort.
Now the interesting thing is that Seachem documents that Matrix provides a home for both aerobic AND anaerobic bacteria and also handles nitrates. So far they are the only bio-ceramic vendor making such a claim.
