ya, out house was built in 1908.... When I moved in I was amazed at how far my tank was off!!! luckily we have a mini wood shop in the basement and we were able to build huge "wedges" for lack of a better word for each of my tanks that leveled the floor and yet had continous contact so there was no chance of bowing from a shim on one side.
