Sorry, forgot to mention that it's a 30 Long model, so the tank is, in fact, 36" long. The fixture has 2x250w halides and 2x65w actinic pc bulbs. I'm toying with building a chiller using an old cube fridge I've got in the garage. I really don't have $500 to throw down on a chiller right now, but I really want to start growing some nice sps corals.
