Leveling a cylinder

[siricosm]

I am installing a 300 liter stainless cylinder, and it is not quite level. The floor is level, but there is a very small tilt on the casing at the bottom, maybe 1/4 inch, but enough to make it look dodgy against the plumb wall. The cylinder does not have metal feet or anything, it appears to just be encased in rigid foam, which means I can't really just shim it on one side, since it looks like the entire bottom needs to sit on something flat.

Any ideas how to make it sit level?

Install on 3/4 ply and level/shim that way?

Paving slab or timber

Another one for making a ply platform that is out of level , to correct the tilt.
