Leveling a tank

[mumra]

Does anyone have experience leveling large tanks? I have a Waterbox 220 that for some reason is about a 1/4" out of level. I have the little feet on the bottom maxed out to the proper sides and you would think being in a basement it would be a firmer and flatter floor be easy to level. But alas it is not. I have a pro I can hire but damn it's expensive.

Why not just use wood shim or plastic shims?!
It’s that easy. 1Gallon of water weights about 8lbs. Drain and level using shim and fill back up~

Sorry I left that out. I have quite a lot of shims under it now.
