I just purchased a 55 gallon tank 48"X12"X18" I am thinking about making it a reef tank because I am bored with freshwater, I have done alot of reading but I am still open for suggestions. The task at hand right now is finding the correct lighting, Im debating on weather to get the CURRENT USA ORBIT model or the 2006 ODYSSEA light fixture. The ODYSSEA model is alot cheaper than the CURRENT USA model.
