I know this topic has been beaten to death,how many of you have second floor tanks.. I want a deep blue 75 on a wood cabinet stand it will be on the outside wall,not sure which way the joists run but i think it would be the shortest distance because the house is long not wide its a 2 family brick.I was gonna go small like a 40 breeder but my sump is a trigger systems ruby 36 and wont fit in a stand for a 40 breeder,I also think i would soon outgrow a 40. I was gonna get a 90 but im not gonna chance it.Thanks SteveZ
