So what is the important part of the lighting system. I know bulbs, but how different are the fixtures? Can really good bulbs go into a cheap fixture? Other than reflector design, what's the difference?
To go reef you will need at lerast a 4 bulb fixture. The reflectors are very important when picking one though, individual reflectors will give you the most out of the bulbs. I like ATI bulbs myself, great color and my corals love them. At only a couple bucks more a bulb it's a worthwhile investment.
