I thought it was easy to use AC500 like Erik suggested since I began with one myself. But I'd create a custom hood since its basically a easy dimension and get a DIY retro fit kit, then again thats if your good at DIY. If so take precaution on the size of the AC500 and the fixture that would be on it when the hood gets created. For lighting, what are you looking for? And what corals do plan to keep?
