My wife, bless her heart, ran into something similar to that a couple years ago. I had a couple 55G freshwater tanks and I had made the passing comment that I would like to get into saltwater. For Christmas a couple years ago she got me an AGA 10G tank 'setup' and specifically told them she wanted to set it up for saltwater. It was the tank, a heater, some salt and various other things. The hood/light combo that it came with was the cheap plastic hood that you could screw an incandescent light into.
