Foam under rimless tank!!!HELP

[vio]

The main concern will be :
If your stand is level on diagonal, not just Wide and Long. I hope you fine.

Diagonally it's off a hair but I plan on shimming it.

Again, my stand is level but the plywood top is full of imperfections, and now I'm noticing I drilled in some spots where the trim will be laying on the plywood. Idk what to do now.
