Apartment + Big Tank = ?

[bulletsworld]

Yeah highrises uses concrete floors for sure. Yup know mine is only wood sticks. O.k maybe not sticks, then again how would I know.

And adding a 150 gal (sumpless) might be dangerous since it doesn't help that my apartment has shifted and all my doors & windows are a bit crooked. But hey every building shifts and settles..right?

My tank right now (77 gal) not being fully leveled (building settling). I wonder if the water settling (1"off from one side) a bit more on one side of my tank would be enough to bust the glass seals open? Or maybe be worst if 150gal? Should I push the max? Then again what is the max for a 4th level walk up apartment? Are my eyes to big for my apartment?
