Fish, plants, and some natural decor all contribute some physical waste to your aquarium. Mechanical filtration takes care of trapping unwanted debris, keeping water clear and your aquarium clean.

Biological filtration occurs when natural living bacteria converts the biological waste created by fish and other organisms in an aquarium into a form other bacteria use and remove from the water. Regular cleaning and replacement of mechanical media, such as foam, helps promote better conditions for the growth and prosperity of these beneficial bacteria.

Fluval Bio-Foam pads provide both mechanical and biological filtration.
