These quiet and efficient filtration devices come equipped with the optional spray bar attachment for wider range output or use the traditional one-way spray for stronger concentrated water flow. Each filter uses a dense sponge for maximum mechanical filtration. Water RETURN The IFE Series allows for multiple water return options. The Spray Bar feature is adjustable to control water flow and swivels left to right. When the Spray Bar is removed and capped the Water Curtain feature becomes available for use. The larger models of the IFE Series offer water return from the bottom of the unit as well. The Bottom Return feature of the IFE is a true innovation keeping organics suspended and pout of cracks and crevices.

This innovation helps to create an over-all current keeping organics suspended for the filter to pick up. The larger models of the IFE Series have an included, self-adjusting surface skimmer which promotes gas exchange, removes surface scum, and aids in keeping a stable pH. MEDIA COMPARTMENTS The IFE Series uses a bottom-mounted pump to move water thru and past multiple filtration compartments. Multiple filtration compartments allow for complete customization of filtration media. All models of the IFE Series come with AquaTop Filter Sponges and AquaTop's Activated Carbon. Biological Filtration can be achieved when using AquaTop's ceramic rings.The Aqueon Quietflow Internal Filter is a versatile filter that can be used in an array of aquariums.
