Does the right front corner of the stand lift slightly off the floor, too?
I think as long as you're shimming the stand (and not the tank) to get it level, you should be fine.
That said, I have no idea what I'm talking about, so, um ... yeah, don't listen to me.
But hey, it looks like it's gonna be a wicked little setup once it's going. Good luck, and can't wait to see it in person.
