Abstract: A filter for aquarium operating in accordance with the lifting-lowering principle comprises a housing with at least one filter compartment for a filter material, a pump which aspirates water after passing through the filter compartment through a suction conduit and supplies the water back into an aquarium, at least one auxiliary chamber supplied with water and a float-controlled valve device controlling an outlet of the auxiliary chamber and communicating with the suction conduit, an auxiliary housing in which the auxiliary chamber is provided and supplied with water filtered after passing of the filter compartment in accordance with the principle of communicating pipes. A passage which is connected with the suction conduit has a valve opening which is alternatingly closeable and openable by a float-controlled valve closing member of the valve device. In another embodiment, a supply is formed as a passage which passes through the filter compartment and is sealed from the latter and opens in a bottom chamber provided in the housing under a lowermost one of the filter compartments, so that the aspiration of the supplied water is performed from below and from the bottom chamber through the filter compartment upwardly with accompanying filtering.
