So there's a chance I could be looking to move from my current 75g setup (36"x24"x20") to something 4' wide, either 120g or maybe 150g sometime this summer. The biggest obstacle I see to doing this is I live on the second floor of a loft style building that doesn't have an elevator. It's quite a few stairs to manage. I was able to get my 75 up the stairs with just myself and another pretty flabby friend, but something substantially heavier could be a real challenge. For people who've moved tanks up and down stairs, how difficult and how many people would it take to get something like a euro-braced CDA 120 or 150 up the equivalent of 2 stories worth of stairs?
