Well, I currently have a 75 gallon tank, and a 27 gallon marineland cube, both are reefs. I am in the process of renovating my room, and I am trying to find a store around the museum campus area, or between home and there that has a 24x24x24 reef ready cube that I could buy next week when I take a trip to the shedd aquarium. That tank will become an in wall tank in the room once I start building the walls in there.
