Warped tank

[etcbrown]

I bought a 150 gallon tank real cheap on craigslist but when I got it home I see that it is warped from being placed on an uneven surface. Question is: Will it straighten itself out if placed on an even surface over time? It is a glass tank 48x24x30 and the stand (also warped) is a standard LFS pine jobber.

Anybody ever deal with this?

ive never seen a glass tank warp.......

Glass is actually a liquid so it's not too far out that its warped. In really old houses the glass is thicker at the bottom than the top. Doesn't really help though...... I'm guessing you haven't filled it up yet? I would imagine if its filled that the weight would unwarp it.

way back when glass was made differently so the old houses dont have uniform glass as we do today,, so naturally there will be different thicknesses in old windows.

Macattack is correct, glass will in fact warp and even flow given enough time. The windows in the old north church in Boston (the one where they hung one lantern if by land and two if by sea during Paul Revere's ride) has original windows from the 1600's and they are indeed now thicker at the bottom than at the top. And it is not due to manufacturing but rather to gravity.

I have also seen a vodka bottle with the neck stuck in a barbed wire fence bend the neck of the bottle 90 degrees over the course of 50-60 years. So it is no stretch that over 1000 pounds of water will twist and bend a half inch thick sheet of glass over the course of a year or two.

I don't have any pictures currently but I estimate the left rear and right front corners are about .2 inch higher than the opposing corners.
