Anything at all about corals

[justinl]

Hey Im new to the hobby and don't yet plan on a reef system but was wondering anyways. Always good to know. So how do you take care of these things? Do you have to add anything to the water (nutrients, additives, whatever)? Lighting? what are your fave corals? What about their biology (frags, lifecycle, other interesting tidbits)?

I also keep hearing people say that they get most of their nutrients from photosynthesis and the rest from the water column. What?! From what Ive learned in biology, photosynthesis provides nothing but energy... right?

PS. damn. I almost had all the letters in the title start with "a"
