TetraTec IN filters contain a foam sponge, through which aquarium water is recirculated. This sponge acts as both a mechanical filter, straining out particles of solid waste, and as a biological filter. As water is pumped out of the filter, it draws in air through a 'venturi' attachment, thus helping to re-oxygenate the water.
