A filter arrangement for an aquarium is disclosed. The filter arrangement can include a filter housing assembly, a pump assembly, and a transfer tube assembly. In one aspect, the housing assembly and the pump assembly are separately constructed assemblies that are connected to each other via a first dampening member to prevent vibration and sound from being transmitted from the pump assembly to the filter housing assembly. The filter arrangement can further include a second dampening member connecting the pump assembly with the transfer tube assembly to further prevent vibration and sound from being transmitted from the pump assembly to the filter housing assembly. A third dampening member can be provided at a location where the transfer tube assembly is supported within the filter housing assembly to further isolate vibration and sound from being transmitted from the pump assembly to the filter housing assembly via the transfer tube assembly.

Aquarium filter arrangement with vibration isolation

An aquarium filter arrangement including a filter housing and a filter cartridge having self-spacing structure. The self-spacing structure being designed to automatically space the filter cartridge in an operable filtering position. The operable filtering position being a position at which the filter cartridge is seated against a single rib formed in the housing.

Filter with self-positioning cartridge arrangement

A filter cartridge including a filtering body having first and second porous filter walls. The second porous filter wall having a density that is different than the first porous filter wall. The density of the second porous filter wall being defined by interstitial spaces. The filter cartridge further including discrete chemically filtering particles that are captured within the interstitial spaces of the second porous filter wall when the filtering body is in a vertical filtering orientation.

Filter cartridge construction with carbon profile

A filter cartridge assembly including a carrier and a filter element. The carrier including a water collection cup that collects water from the filter element when the filter cartridge assembly is held in an inverted orientation.

Filter cartridge assembly with water collection

An aquarium filter having a filter housing with a rounded bottom. The filter housing including a housing input that directs water into an interior chamber such that the water sweeps across the rounded bottom to reduce or eliminate dead spots and reduce particulate settlement.
