Do you think Ill be ok

[Phatboy]

I have a single bulb 400w 20k MH right now. This thing is bright.:xd: I had it for a short tank, but I now have a 72" long 120. I know this light wont be optimal for such a long tank.

Primarily I am going to have softies, and just a few SPS. Do you think this 400w with some T5 supplementation will be enough for a tank this long?

Id rather go with two 250w MHs or all T5, but no money for that right now.

I think it might be to strong at the center. I don't think it would spread enough across the tank

Im thinking the same thing, I just cant seem to unload this 400w unit. Noone wants it.
