Aquarium filter with stacked filter rings - has inlet chamber under disc supporting filter rings

Abstract

Abstract A central cylindrical compartment (4) forms a second compartment, and is joined at the base to a disc (5) resting on the annular rim (6). The disc (5) has perforations (7) which join the space (8) at the bottom of the trough with the first compartment containing the stack of annular filters (9). An annular flange (10) of the lid (2) keeps the stack in position. A preferably non-corrodible metal projection (11) is held by a nut (12) and has a back disc-shaped part (13) separated from the trough-wall by an annular joint (14) or mastic. The bottom trough wall has an annular ledge (15) and interior thread (16) corresponding to the outside thread of the side wall (17) of the removable base (3) which is unscrewed by means of a bolt (18).
