1 1/2" thick, two overflow box position for tank to be viewed from both sides. Very clean. No serious scratches. Plan was to cut the tank up for viewing windows but never did it. Must sell. Need space. Best offer.
This skyscraper was not cheap to build due to the non-standard 5' wide sheet. Those who fear height can learn to adjust
Haha! I just finished my 1100g build so I'm not ready to take on a new project. Its certainly an appealing tank.
