I'm looking into purchasing this 180 gallon tank but there were a couple of things that I'm a little worried about... overall, it looks like the tank was re-sealed/re-built... nevertheless, these are the things that are giving me second thoughts.
1) On one of the sides... there appears to be a bubble in the glass but the sealing is over it.
2) The former owner build metal crossbars (2 total - they were welded together to lay on the top to clamp the back and front) that go over the top... the normal plastic one on brand new tanks are not there. When the tank isn't filled... the crossbars can be moved when the tank is empty but the current owner mentioned that when it's filled with water... it doesn't move anymore.
Pics of the bubble are below.... thoughts? Should I be worried if I purchase the tank?
