Hang On Back filtration is provided by hang-on rear filters, which attach to the aquarium’s rims.

The majority of hang-on back filters have a powerful water output that cascades onto the surface.

This can be used as an aeration system, saving you money on a separate system that would detract from the natural appearance of an aquarium.
