Because of the way we build these 2x4 stands, I'd recommend you use some styro between the tank and stand. It will take up a lot, but not all, of the variances between the 2. Has saved many a people broken tanks
 This stuff, or something similar. 1" is the norm and most use the pink stuff 
It's also a temperature insulator for the tank, so it's nice to have
