24" or 36" T5?

[Hentz]

Hey guys. My ZEOvit sps tank has been running for a while now. Tank is 36" long though I'm currently running a 24" ATI 6x24 Dimmable.
My aquascape is 24" long, though was wondering if it would be worth jumping up to a 36" ATI unit?

I think 36" is better for a 36" tank. Your corals will grow out wider than the rock. Keep in mind that 36" fixtures hold bulbs that are about 33" long.

+1 on this.

I have the 6x39w dimmable ATI fixture over an 36" tank and am very happy with the coverage. I also have a reef bright mounted to the light for supplemental lighting.

Agree with the others go the larger light, T5 intensity drops off on the ends aswell so if your light is longer than your scape the corals on the outskirts will get some nice light then.
