20g (24"L 12"D 16"T) was a glass holes overflow kit that was installed. It's 3/4" with bulkheads siliconed and included. I never ended up setting this up. Moved and ended up setting up a different one.
Back is painted black, in retrospect kind of wish I didn't put that there but it can be removed easily with a razorblade if you desire.
Only looking for $60 or possible trade for Zoa/Paly/Unique Mushrooms. My tank is fairly new still so only trading for hardier corals at the moment.
