I have a 190 gallon glass tank with homemade wood stand available for $200.00
This isn't a pretty tank. It has chips and scratches, but it holds water just fine. I have it filled in my garage (it's housing snails and clams for my puffer at the moment).
The tank is also drilled for overflows in the back. They are currently plugged, but can be easily pulled to use a sump setup.
Pm or call with any questions. 586-524-4740
