I have an Eheim 2211 classic canister filter, 40 gal size. It’s in great condition, used less than a year, selling because I went to a filterless set up with that tank.
Comes with canister filter, tubing, inlet and outlet pipes, suction cups, and some nylon scrubbers I use as my filter media (durable, reusable, great surface area for bacteria, and don’t clog as easily).
