Abstract
An aquarium filter is provided having a first annular chamber and an inlet or near the top of the chamber. The inlet is constructed and positioned to direct water into the chamber in a swirling direction, concentric with the annular wall. The first chamber also includes a first water outlet at the top of the chamber for filtered water to exit the chamber. The first chamber also includes a waste outlet at the bottom of the chamber. As water enters the first chamber from the inlet, it swirls in the chamber, creating a vortex. Particles within the water are forced against the annular wall, slide down the wall and migrate towards the waste outlet at the bottom of the chamber. A collector, such as a simple collection pot can be coupled to the waste outlet and particles separated from the water will collect in the pot. A selectively closeable cleaning outlet at or near the bottom of the collection pot can be used to empty the material collected there.
