More decisions, I love it, the more experince the better so I got...
Macronut, reefergeorge and cdbias2 - digging the 125 long, but watching on the center brace and better fish compatibilty.
Otogi-started the 90 G and now craving the 200+

.
rbtwo4, MHannon, and cdbias2- liking the 120. Aquascaping and lighting pluses.
carb850- cost wise 90g is the way.
I am in the same situation carb850 was in. 90 vs. 120. I already built a stand for a 90G and was gonna go coast to coast with my tank but found out I couldn't drill my tank because it was tempered. Then I started looking at RR style tanks and really like it because not really into HOB overflows. The LFS is willing to take my 90g back for store credit five months after the fact, which is pretty cool. I threw some rocks on my stand just to see how it would look and like most of you have mention, it is a little narrow.
The worst part I gotta figure out how to extend the stand 6" back.
My plan is to start with FOWLR (really light) and has I gain more experience get into mix reef (more into the reef thing).
I have already purchase a H&S A150 and Tek light 6 X 54w fixture,
basically have until this coming wednesday to place my order.
