Does live rock remove nitrates?

[Delphinus]

I'll pose a corollary question then, why do other long running systems, when even feeding "lightly" and lightly stocked, always show trace amount of nitrates (namely my tanks ... or in some cases, show ridiculous amounts of nitrates)?

I'll say one thing about carbon dosing though, 3 weeks of "Polyp Laps Reef-resh" has done what a year of running sulfur could not, and for the first time in well over a year I have sub-10 nitrate readings in my ritteri tank. Wish I knew what the difference was with this tank and its resistance/resilience to denitrification... it's really weird.

Tony, does your theory about different rock perhaps come into play here? Maybe your rock is not porous enough?

Brad thanks for a great thread.

Following your thought above. I started to think about this. There are so many places we now get LR from. A lot is farmed line stone. Other Rock is from a dead or deep reef. I'm wondering if the good porous stuff is becoming harder and hard to find.
I have already been hitting the books but have not hit on the article that started my understanding that LR alone does not complete the nitrogen cycle. In a closed reef system.

OK so I wasn't able to dig up anything concrete yet. But I'll be back into the books tomorrow.

Jason, did you read that link? Ron and Eric are supposedly doing further research, so depending on when that link was done, they may have completed it by now. Maybe I'll try to ask one of them if they have more info.

The last few shipments of live rock I bought were crap. Jakarta maybe? I can't remember. All I know is my first tanks with premium fiji were awesome, before I discovered good skimmers even..

do you see any difference inNO3 with it's use? Or is it combined in existing setups?

Don't have them anymore Brad, and never had algae enough to want to measure. The tanks I mention were 100% fiji premium.

All I know is that is my rock of choice.

Ya, I never went wrong with the fiji. The jakarta I see now looks like it came from someone's garden.
