Theiling Rollermat Aquarium Filter

Got this Theiling Rollermat filter for sale. It's a mechanical fleece filter for aquariums that helps keep the water crystal clear by removing waste before it breaks down. It's been used and has some salt creep and dust on it, but these things are built like tanks. Great for anyone tired of cleaning filter socks every few days. Selling as is, what you see in the photo is what you get.
