I would suggest researching the corals you want to keep first. Then, based on that, buy your lighting. If you decide you want to keep SPS
corals, you will be far better off to go ahead and buy a MH
lighting system to start with. If you want to stick with soft corals, PC
would be fine. The two are about equal as far as light output goes. Another option you might want to look into is T-5's.
