Well, still no update on the defective tank. We ended up removing the self leveling mat thinking that was the issue, but no, the bottom panel of the tank was glued with a curve. Both ends of the tank are flat where the side glass and bottom meet up, but in the middle where the bottom panel is glued to the front and back glass, there is a noticeable “lip.” This is causing all the weight to sit on the middle of the bottom glass panel with both ends raised up. Unfortunately, our LFS has been unhelpful. We tried to simply exchange the tank but were told that we had to go through the manufacturer to do so. So we emailed Planet Aquariums and sent a Facebook message (which was opened) a week ago and have heard nothing. Confidence is fading quickly lol
