Does live rock remove nitrates?

Well LR must do something as I'm BB and test usually 0.0 or 0.2 NO3 (or got a bum Salifert testkit).

And I believe this is typical of many (most?) tanks. Isn't it?

I beleive it is fairly typical... except for perhaps in more heavily fed tanks at least...

Yeah, I'm wondering about porosity. It's funny that you started this thread because I was basically wondering the same things and the thought had occured to me just today about the rock density.

Well, I've gone through bouts where I've fed really heavy, no change in NO3. Maybe I'm just lucky?

I guess I bring this up now after that comment I saw, and the fact I need to buy new rock in th enext few weeks.
