My 375gal all glass tank will arrive in the next couple of weeks. I has an external coast-to-coast overflow. The overflow is smooth (no teeth), so the tank has to be perfectly level - my floor is not even close. It'll probably take 3/8" of shims under the stand, in some places. The stand is made of 1 1/2" iron. My question - what would you suggest as the best material to use for the shims? I would even welcome some hints on how to get 'er done. ![Cool :cool: :cool:](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f60e.png)
