Slanted floor problem

[SomeGoby]

I just got a new read sea max e 170 and noticed that the top of the tank is roughly 1.25 in farther away from the wall than the bottom of my stand is, what can i do about this while still keeping it stable?

Use a level to determine what's not square....the wall or the floor. If it's the floor, shim the bottom of the stand to level it out.

I add just just enough water (couple inches) so you can eyeball the bottom rim against the water then shim it.

What do you think the best shim would be to use im afraid that wood might split

I've used plastic toilet bowl shims.

Plastic here too, they are easier to trim up.
I would add an aquarium mat as well.
