Fluval U1

The Fluval U1 is a discreet and efficient internal filter designed for aquariums up to 45 litres, consuming just 3.5 watts while delivering a gentle 200 litres per hour of filtered flow. Its adjustable directional output allows the current to be aimed anywhere in the tank, promoting even water circulation and preventing dead spots. The multi-stage filter cartridge handles mechanical, chemical, and biological filtration in a compact housing. Suction cups provide secure mounting in any position — vertical, horizontal, or angled — adding flexibility for unconventional aquascape designs. A great choice for nano tanks, betta aquariums, and small shrimp setups.
