I am all but lost in my effort to figure out what is the best options for lighting a 90 gallon reef tank. I do not want to be restricted in what I can keep by what light I have, so this needs to be a wise choice. I know that it would be easy to say just buy one of the really expensive units, but I am convinced that it can be done just as good for a fraction of the cost. Originally I was sold on the Outer Orbit fixture from current. At a price point of about $800 it seemed like the best choice for the 24 hour system I wanted. Now after trying to do some research, I'm more confused than ever. I would entertain the thought of pendants or retro kits, but I dont even know where to start. HELP!
