Help leveling my tank.

[NYCTURBO]

I have a 1/2 inch gap to level on one side of my 90 gallon tank stand what is the best way to do do it? I don't want to see the gap at the bottom of the stand any advice? I know I can use shims but where do I get them big enough to fill in the complete bottom of the stand without using multiple shims?

I stack vinyl floor tiles on top of each other when leveling the stand on all 4 corners of the stand before the tank goes on.

Wood shingles for walls and roofs are thicker than shims, maybe not half an inch though. You want a material that does not compress.
