Bowing

I know my 135 acrylic Aquarium is bowing, but I have a couple of questions. How exactly do you measure the bow? If I placed a 48” level lengthwise across my tank which is 72” long, in the center of the viewing panel, I’m getting about a 1/4” bow on each side. If I take the level vertically across the viewing panel it’s close to 2 inches keeping the level flush against the bottom portion of the tank. Any input would be appreciated.

Is that right, 2 inches? That seems excessive. Have any supports for the tank broken? The 1/4" bowing is well within
what I would call normal.

Can you post a picture?

No supports have broken. Vertically if I center the level across the middle, it’s probably closer to an inch on each end. The two inches was vertically from the bottom of the tank to the greatest gap point at the other end, so exponentially that would continue to increase. I’ll try to snap a pic
