Ive seen worse lol… could be better tho also. I dont think that plank of wood would matter as much if it were placed on top of a proper stand. The mat bothers me as well as how un level the top of that futniture/board combo is. Will it explode… probably not, acrylic is pretty strong even at 1/4-3/8”… looks like its already a done deal tho as the tank is set up. How temporary is it? Any zoomed out pics of the setup/furniture its sitting on?
