I just ordered an 252 gallon tank (80 x 26 x28) )with a metal stand using 2 x 2 x 1/4 angle bar, I noticed that the center part of the metal bar is bending due to the weight of the tank, there is no center post as there is another tank at the bottom. Would another 2 x 2 x 1/4 spanning the whole length of the stand welded across be enough to support the weight ?. Water has been reduced to 1/2 to prevent catastrophe
