Hello, I'm very excited because I just purchased my Cade 600 Pro Reef tank, but I have no idea what kind of light would be best for it. It's a 24"X27"X24 cube tank. I am wanting to have fish and some easy corals, like LPS's, but may want to try a few SPS corals and/or nems later. Do you all have recommendations for a light that would be suitable? I prefer one that can be mounted on the tank instead of hung, and budget is a consideration, since I spent more on the tank than I really wanted to. Is buying a 2nd hand light an option? Or would I be better off going with a new light? Thanks for any help!
