Yeah, you're going to have to get rid of the CC star, definately not reef safe. What kind of corals do you plan on keeping, just softies? There are a million opinions on lighting, but if you just want LPS and softie corals, VHO and power compact lighting is fine. And remember, getting the bare minimum usually isn't the way to go, as you limit yourself, and sometimes have to shell out for all new lighting, etc should you want to upgrade. Plan it out, and make a budget to see how much you can spend. Getting decent VHO or PC lighting for a 75 gallon tank will cost a few hundred bucks. Do a search on the board to see other peoples opinions on lighting.
