Fixed.... A man, a woman, a child, a cichlid​, and a tank (working title)...
Sweet. Even if it holds water after fixing the frame, you might still consider the fiberglass, just for the long term peace of mind.I'm going to back out each screw on the 2x6 frame then squirt some liquid nails in then screw it back in then put some over the screw head. After that all dries, I will use the remaining 2 gallons of liquid rubber on the frame. If that doesn't work, I'll be investigating how to use a chop gun and fiberglass the entire tank!!!
I had filled over each screw head with liquid nails throughout the rest of the build. I got lazy and skipped that step stupidly with the frame around the window.
