180g with sweet light

[GRUN]

always have had well planted tanks but as the tanks get bigger the are harder to light until now just popped a 150 wat high pressure sodium bulb on my 180 g the bulb only projects on about a third of the tank so i would assume it has almost 3 wats per gal on the section of the tank.will post b4 and after pics next week wen i gets my camera

not really true. bigger tank be come easy to light since you need less light over them then smaller tanks. depending on what you want i would just go with some t5 ho.
