I was close to that, but had to add a bit more when I restructured. But even with that little, NO3 has always been 0, so it's enough for filtration.

Do you still have your shallow sand bed Brad?

I do in this tank, but did not in the last 2 setups. Same results either way.

Can't forget the filtration provided by all those granules of sand as well. That's a lot of surface area right there.

You have a shallow sandbed also? I have to go back and look again.

Yes. My sandbed is about 1/2 to 1". Simply for aesthetics but but the sand grains do provide surface area for biological filtration as well.
