| Re: 87G AGA Eventual reef Being 3mm out of square over 1.2 meters isn't too far out of whack.
Have you tried turning the stand upside down to see if the top is square/flat?
It would be preferable to shim between the stand and floor as boozeman suggested. The tank would be better off on the flattest surface possible.
