Hey guys I have a new tank from my cousin that is 5x2x2. I posted a thread awhile back saying it wasy 6x2x2 but I meant 5x2x2. I think thats about 150 gallons. Well I have a MH set up thats 2x175 and a 55w and 96 wat pc bulbs. That would be equal to 501 watts. Do you guys think it would work if I just use the MH and the 55 watt bulb only? The tank is not that tall Im planning to hook the MH set up to the ceiling. I also have Co2 injected which I would hope help if I dont use the 96 watt one.
