Sorry for your situation...let me help

, lets just ship the tank to my house, where there is no 90 degree turn to worry about, and I'll set it up in MY basement (just let me move my couch out of the way...there we go, plenty of space- honey, don't worry about the couch in the hall...the cushions will be better on our joints, you know less stress walking on the padded couch then the floor and all)...
JUST HURRY AND SHIP IT BEFORE MY WIFE FINDS OUT!!!
That would solve all our problems, give me your tanks!
It's a win-win-win, you no longer have to stress about upstairs, 90 degree turns etc, I get a bigger tank in my living room (next to the 72 inch 125), and you get the warm fuzzies that you helped your "fellow man" (namely me) out, come on, what to you say, deal!
pm me for the shipping address!
