And I'm not certain you need a carbon source with these bacteria, now you're gonna make me have to hit the books again.  |
Nitrate is removed with water changes but more importantly organics are removed before they break down into nitrates with a good skimmer. Also a refugium can work fairly well at removing nitrates. I really doubt your rock is doing very much, maybe some but very little.
