Used 270 gallon acrylic tank. The dimensions are 6' x 2' x 3' and the acrylic sides are 3/4" thick. My sister recently bought a very upscale home and as the previous owners were downsizing considerably, they left the tank and thus I am selling it for my sister. I have included pics of the tanks plumbing (on the side of the unit), as I'm not sure how exactly to describe it/name it. Also, a large light (pictured) will be included with the purchase. Any q's please let me know. $1000 - pick up only.
