. -i've post about my 220g sagging and all that, take look if you can find it, is "will my 220g crash or bent my house" something like that, of course is not going to collapse, but for sure will sag, i put 2 x 4 under my living room,
I think that is the issue though. yes, it probably will not collapse. but it may sag.
if your floor sags under the weight of your tank, either the tank is too big (heavy) for the floor or the floor needed to be reinforced even more.
sagging floors are not good.
I think you would still be shy!
