Hi, I purchased a used tenecor aquarium it is 71"Lx30"Wx32"H. It is made with 1/2" acrylic and the top brace is 1". All the seams look good besides this one in the bottom right corner. I have leaked tested it and holds water good there is a decent amount of bowing on the front and back panels when full. Just trying to get some opinions on this Seam.
