An aquarium filter system comprising a pump, a manually positionable valve assembly, and one or a plurality of interchangeable filter cartridges. The filter cartridges are interchangeable and replaceable without the need to suspend water flow. The filter cartridges may be readily repositioned relative to their location from the pump. In method form, a method of changing filter cartridges in an aquarium filter is disclosed. The method comprises supplying a pump and pumping water to provide a continuous flow of water from the aquarium to one or a plurality of removable filter cartridges. This is followed by isolating any one or plurality of the filter cartridges from the flow of water and replacing any one or plurality of filter cartridges with one or a plurality of unused filter cartridges. This is all accomplished under conditions such that the continuous flow of water is uninterrupted.
An aquarium filter system for filtration of water, comprising a pump, a manually positionable valve assembly comprising a plurality of diverters and a plurality of interchangeable filter cartridges, said filter cartridges interchangeable without the need to suspend water flow wherein said diverters each independently control the flow of water to said filter cartridges such that the system provides filtration of said water through one of said filter cartridges while one of said filter cartridges is replaced.
