Duetto Multi-Filter is a compact internal filter that efficiently packs maximum features in minimum space.The multi-filter internal chamber has separate components for mechanical, chemical, and biological filtration, permitting easy replacement and cleaning of the chemical and mechanical filter without disturbing the biological filter.The aeration feature mixes filtered air with pumped water to provide complete aeration, improving the oxygen/carbon dioxide exchange. The multiple output adapters allow either flat output for easy direction of water, or round output for easy connection to flexible tubing.The Duetto Multi-Filter is totally submersible and can be positioned vertically against the aquarium wall, or horizontally on the floor of an aquarium or terrarium.Can be adjusted for minimum or maximum flow.
