Ok, I have my new 30 gallon set up. its 30 inches long, and the only light fixture that i saw online was this 30 inch 2x31 watt T5 lighting. I bought this light fixture for a total of 120 bucks including shipping. I am pretty sure this is low wattage in lighting, but i could not find any other light fixtures with more wattage than this one. The ones with higher wattage are always longer than 30". where do people get their lights? I see many people with 30inch long tanks with more than 2x31 watts. I am trying to keep soft corals such as mushrooms and zoanthids. is this enough?
