FLUVAL U2 Internal Filter

FLUVAL U2 Internal Filter is a versatile and powerful internal aquarium filter designed to provide exceptional 3-stage filtration, improved water circulation, and essential oxygenation for healthy aquatic environments. Suitable for aquariums up to 110 litres, the Fluval U2 is an ideal choice when external filtration is not practical, delivering reliable mechanical, chemical, and biological filtration in a compact design.

Whether used as the primary filter in smaller aquariums or as supplementary filtration in larger tanks, the Fluval U2 offers flexible installation options. It can be positioned horizontally to suit shallow aquariums, low water level setups, or to create an attractive waterfall effect, while vertical placement against the aquarium wall helps generate customised currents and flow patterns.

Featuring an adjustable 3-way flow control system, the U2 allows you to tailor water movement to the needs of your fish and aquatic life. The top output enhances circulation and oxygenation, the integrated spray bar provides a gentle and even flow, and the bottom output creates deep-water agitation for improved overall water quality.
