Leveling the middle/centre of a stand

[PranK]

Hi all,

About to move a tank into my garage and while I have no problem leveling the tank on the outer edges with shims, what about the inner parts?

My stand is a typical undressed 6 leg stand but I have a floor on the bottom for a sump which is about 4 inches off the ground and which has 2x4 braces under it. How can I make sure those braces are supported also?

Thanks

Christian

Actually, if I feel the braces across the bottom they are all slightly raised. I'm not sure they even touch the ground.
