Fish tank/Filter/Supplies

Sorry, I meant to ask if you have the actual working filter unit itself? (Do you have any carbon left) Id ben looking for a rectangular 30 gallon tank, I’d have to see if I can fit a 36" wide tank somewhere though. Right now I have a hexagonal one so it’s tall and doesn’t take up much room but I need more length for the plecos on the bottom of the tank.
Do you have a stand for it by any chance to sell?
