Fluval U3

The Fluval U3 internal filter provides thorough mechanical, chemical, and biological filtration for aquariums up to 150 litres, running at 600 litres per hour with an 11-watt power draw. Multi-directional output adjustment ensures water movement reaches every corner of the tank, eliminating stagnation and supporting gaseous exchange. The expanded media basket holds more filtration material than smaller U-series models, supporting a larger biological filter colony for tanks with moderate bioloads. Tool-free media access makes cleaning and media replacement quick and easy during regular maintenance. Ideal for medium community aquariums, barb and tetra tanks, and moderately planted setups.
