300 gallon aquarium top bowing

[TonyD1988]

Good morning R2R. I am not 100% sure if this constitutes an emergency or not but here's my situation. I have a 300 gallon truvu acrylic aquarium I am in the process of setting up. I have the display about 80 percent full of water right now. Long story short last night I had to lay on top of the tank (its a bonded acrylic top with 4 cutouts for access) so reach down into the overflow as one of my bulkheads started randomly leaking and the nut is on the inside. Well when I got back down I noticed the center had bowed in. I laid a a level across it from front to back in the center of the tank and there's about a 1/4 to 1/3 inch gap from the level to the top of the tank now. The left and right sides of the tank didn't seem to bow in much if any. Is this going to be an issue? Should I drain all the water out and try to get the top straightened out?

As long as there has been no damage to the seems where top is bonded to side panels it should be fine and Im guessing that small deflection of the top panel will straighten out when tank is completely filled.
