Starting to gather things for my 115 aggressive build. it is 74 long by 20 wide. I'm having a metal stand built for it but was wanting to make the stand a inch shorter in length and a 1/2 in short he'd in width so that once I put my 1/2 wood on the 3 side sit will be flush and super clean... will doing this and having the edges of the tank hang off stand effect the integrity of the aquarium?
