I've been researching zoos on RC and am blown away by the amount of light folks over there keep their zoos under

Pics of their zoos are great, but does a person really need MH lighting to keep them?
I'm thinking that at some point in time, my 28g bowfront no longer be used for seahorses

, but will become available for some other purpose. The thought of a zoanthid species tank comes to mind..... Currently the 28g has one 55w 9325K PC on it. Not enough to get brilliant colours out of zoos, correct?
Does anyone here keep a zoo only tank? If so, what sized tank and what kind of light do you use? Any pics?
TIA
