Is one strip light for a 37 gallon FOLR enough?

[leafyseadragon]

I am planning a 37 gallon FOLR tank and I was wondering about the lightning needs for 20-30 pounds of LR. I already have a single 30" striplight with the original bulb, but this is probably not enough, is it?

I will replace the bulb, once I figure out which one to buy. Since I have room for only one, would it be better to have a 10000K Coralife High Intensity or a combination bulb like the Coralife/Reef Sun 50/50? Given that this tank is rather tall, I am leaning toward the 10000K, since higher temps mean deeper light penetration.

I was also considering a 29 gallon tank which has the same footprint. I would prefer the 37 gallon though, more water means more room for error. Would buying the slightly shorter (18" vs. 22") 29 gallon tank make any difference? Or should I just keep the original bulb, buy the bigger tank and give up the LR? :?

If it were me, I would look into a 10K 30" PC fixture, You can probably do a 65W 10K PC or a Smart light (50/50) and be OK for the tank your comtemplating. As for the size, personally I believe the 29 is a better choic and actually a 30 would be teer than that. The thirty will have more surface area than the other two and the 29 has more surface area per volume.
