Abstract
A water pump including a rotating impeller is located between the two filter chambers, and pumps water from the aquarium tank, via the inlet conduit, into a corridor which communicates with the two filter chambers. The impeller is constructed with relatively closely spaced radially extending blades, each of which is formed of a circular disk. A base edge, or chord, of each blade is inclined upon a frustoconical surface of a central hub of the impeller.
