Anyone here own a Hagen tank that has seems in the corners of the top and bottom frames?,,,,,,,I know this is way they are manufactured, but what gives the tank its strenght?,,,,IMO the frames should be one piece to give the support that is needed, especially in larger tanks where the pressue is greater. So is the tank ok, or should I support it somehow?,,,,all imput is appreciated,,,,,( tank is 108 gal. ) 60x24x18
