I have no idea how much a 700 would tip the scales but the place you get it from can tell you. And yeah no way would it go on a 2nd floor. I had 4 people move my glass cage 240 with cups and it wasnt bad. You get enough people on the tank your good. And build some dollies for the long flat runs through the house and the friends to lift it. Ohh and get a short stand lol
