Abstract
An aquarium filter having a housing unit which is adapted to be mounted onto a wall of an aquarium tank. The housing includes an inlet chamber for receiving contaminated water from the aquarium tank and a filter chamber for filtering the contaminated water from the inlet chamber. A motor unit is supported by the housing and includes stator laminations which can be energized by means of a coil. A removable unitary intake assembly is positioned in the housing. The intake assembly includes an intake tube for supplying the contaminated water from the aquarium tank to the inlet chamber. It also includes a rotor assembly having an impeller mounted on it. The rotor assembly extends into the intake storage chamber and is magnetically coupled to the stator laminations to thereby drive the impeller pump.
