I would not be satisfied if my new ADA tank was that far out of square but I put ADA to pretty high standards because of their much higher cost.
My wife's Mr.Aqua 12 long was not quite perfectly square (and has since developed a leak) but it was also half the price of the ADA 12 long at the retailer we were dealing with, for half the price I can deal with a little crookedness.
