okay stupid question---
 
someone was trying to educate me on ammonia and it's nitrification and then denitrification.
anyone know about corals LPS or SPS breaking down ammonia or even involved in the nitrification section?
there's no articles online or even proof of this even evident. anyone have info on this?

Corals are not involved in the nitrogen cycle, as far as I am concerned. By that, I mean that even if they do have a role in breaking down ammonia, nitrate, nitrite; they play an insignificant role.

The main players of the nitrogen cycle are: aerobic bacteria break down Ammonia into Nitrite, and Nitrite into Nitrate. Anaerobic bacteria then break down the Nitrates in the system into Nitrogen gas, which leaves the system naturally. The aerobic bacteria are found on the surface and in the shallower depths of the sand and rock. The anaerobic bacteria are found in the deeper depths of the sand and rock, where oxygen is limited.

Corals do not harbor the correct bacteria for denitrification; they harbor a form of phytoplankton called zooanthelle which have a symbiotic relationshipo with the corals. The zooanthelle act as a food source for the corals and use photosynthesis to feed themselves. The zooanthelle may use up some of the nitrate and phosphate naturally occuring in the system, but the impact is insignificant.

Hi Wake,

thanks for answering my question. it just affirms my knowledge that i've learned for a while. when I heard this I was completely blown off. Your explanation was exactly what was going through my mind as I was listening to that rubbish. I could not believe my ears, it really just got to me.
