am about to set an office tank, 75 g, 41w x 24.5H X 17.5 D, the tank comes with 2 T5 HO 39W EACH tube total 78w , so i bought another light fixture same set up make the total 156 w, am thinking to get a third one to make it 234w wich will give 3watt / gallon.
the tank is 24.5 inch H and the T5 are 36inch w 5 inch shorter than the tank.
should i get the third light fixture, or should i stay at 2w/g mark
co2 will be used
thanks
