Depends on what you plan on keeping. Fish only not much light. Corals I recommend MH or T5. Mean difference between the MH and the T5 is heat. MH is alot hotter so if you have a canopy you may have to worry about heat issue. On my 120 I run 2 250 watt MH lights and 2 54 watt t5 lights for actinics.
