If you look at my WebCam: worm5406.from-md.com:83 you will see the 120 on the left the 180 in the center and then a 55g on the right. Where the 55, and the RODI, is located, is where the 265 and stand will go. All three tanks will be up and running. Yes the water will be available to all of them.
265 is 7 foot and that wall is 8 foot.
I ordered a LifeReef CaRx.
