AquaTop’s IF-Series of aquarium filters are a great space saving and flexible method of internal filtration. These quiet and efficient filtration devices can be vertically mounted with the included suction cups, and each model has an adjustable water flow. The customizable IF Series also comes equipped with an optional spray bar attachment for a wider range output and an optional Venturi-Line for added oxygenation. The traditional fitting with Venturi-Line option can be capped for stronger concentrated water flow. The submersible IF Filter uses a dense filter sponge for maximum mechanical filtration and comes with a filtration media basket loaded with AquaTop’s Activated Carbon.
