The Fluval U2 (A475), manufactured by Hagen in Italy, is a compact, high-performance internal aquarium filter specifically designed for freshwater aquariums ranging from 110 to 200 liters. Launched in 2010 with model years spanning 2018-2026, this unit offers a comprehensive 3-stage filtration system to ensure crystal clear and healthy aquatic environments. Its robust filtration includes mechanical pre-filtration using a durable foam pad, followed by effective biological purification primarily facilitated by the foam's surface area, and chemical filtration via an included carbon cartridge to remove odors, discolorations, and impurities.
Powering this system is an efficient electric pump that delivers a maximum flow rate of 400 Liters Per Hour (LPH), coupled with adjustable flow control, allowing hobbyists to customize water movement for diverse aquatic inhabitants or planted setups. The unit consumes a remarkably low 6 watts, ensuring energy efficiency during continuous operation. Constructed from durable black plastic with a plastic impeller, the Fluval U2 has a compact footprint (90mm L x 80mm W x 200mm H) and weighs only 0.7 kg, making it highly portable. Installation is straightforward, utilizing included suction cups for secure placement inside the aquarium, and it is fully submersible. This filter is optimally compatible with freshwater, planted aquariums, and is shrimp-safe, ensuring minimal disturbance to delicate species. Key features include an auto-restart function after power interruptions, enhancing reliability. It adheres to CE and RoHS certifications, confirming its quality and environmental compliance.
