Min lighting for corals

[rudy]

My tank is new so I am not going to attempt this for quite some time.

I have 108 6 foot by 18 inch tank. My original thought was a FOWLR tank however my wife really likes the corals and wants me to get a few at least. What kinds of corals are realtively easy to keep? What kind of things should I look for and most of all what kind of lighting will I require?

I do not want to blow the bank on lighting so pretty much looking for a minimum acceptable to grow corals with.

Thanks a lot.
