I think it's on another thread, but get a good book like "The Conscientious Marine Aquarist" by Bob Fenner to learn some of the things to do & why you should do them. This would give you a good foundation of knowledge that you can then add to by asking specific questions to specific problems or areas of interest.
BTW, I think the denitrification the original poster was talking about is the one performed by anaerobic nitrate-consuming bacteria, as opposed to the ones that consume ammonia/nitrite. It's the premise behind deep sand-beds. Personally, I'm not a big fan of deep sand beds, but I still like the look of a shallow layer of sand on the bottom.
