Roddy Conrad uses boulder size feather rocks but in a trickle tower application. Zero nitrates I believe.

I'm at a total loss as to any correlation you're making between feather rock and other medias here.
I'll just go on record in saying that the media that has worked well for me in a shower with no
maintenance is feather rock. It's stayed very clean and required me to do nothing to it going into
it's 9th year in operation. If you want to make that into a negative thing, that's your call. I've not
experienced any of the negatives you suggest, but only the positive of having to do nothing but
enjoy it working on its own.

It's amazing after billions spent worldwide on nitrification and denitrification research the gaps in totally understanding the processes in nature. Every year something new and relevant is published.

Very interesting with the denitrification part.
My spontanous questions: Do I need to give organic carbon source to the denitrification bacteria or the leaked organic matter from the koi food is enough? Will normal sugar (sucrose) do? Will addition of sucrose harm koi?
Many using showers and media such as feather rock and Bacteria House claim along with excellent nitrification additional low or near zero nitrates. Some think the denitrification is happening deep in the media in regions with less oxygen. Others think the excessive splashing is releasing the nitrogen. Multiple studies have disproven the splashing theory. Personally I believe people using these systems that are reporting low or near zero nitrates are correct. It hasn't been lab verified it is shower related.
Normal shower operation and no addition of a carbon source.

There is so much we do not know. The simple Nitrogen cycle circle is outdated.
Recently somebody shared a YouTube video (https://youtu.be/sAVkZ5Xr5IU) about The Anammox Process.

Thanks!
Maybe we can write it down here how much less nitrate our systems are producing than they are supposed to do, also what kind of filter systems we have. Then we will know which of them are better at removing nitrate.
I have calculated to 40% less nitrate produced in my system, based on the amount of food I am adding. I have a simple pressure filter, and some friend here told me that pressure filter is the least efficient.
How I calculated (all are weight/weight):
Proteins contain in average 16% N, which is equivolent to 19% NH3. So 100 g koi food with 30% protein content has 4.8 g N, which will be 5.8 g NH3, 15 g NO2, and 21 g NO3 respectively through the biofilter system. In a volume of 1 m3 it means 6 ppm NH3, 15 ppm NO2 and 21 ppm NO3, respectively.
