A filter for aquarium has a housing having a bottom chamber and at least one filter compartment for a filter material located above the bottom chamber, a supply arranged so that water is supplied from above so as to pass the filter compartment and float to the bottom chamber, a pump for pumping water from the bottom chamber back into the aquarium, so that the filter operates as alternating lifting-lowering filter. Each of the filter compartments has at least one overflow aspiration lifting device with an inlet located at a base side and substantially at a height of a bottom of the filter compartment and an outlet which opens downwardly toward a next one of the filter compartments.
