Fluval U series underwater filters. 3 stage filtration with BIOMAX for superior aquarium water quality.
Stage 1 Foam removes large particles.
Stage 2 Poly/carbon cartridge traps fine debris, improves water clarity and removes impurities.
Stage 3 BIOMAX provides optimal biological filtration efficiency.
Flip-Top access for quick and easy cartridge replacement and three way flow control make the new Fluval U Series the benchmark in underwater filtration.
Fluval U series aquarium filters have the special Flip Top system which allows filter cartridges to be removed while the filter continues to operate in your aquarium.
The Fluval U series filters can create a surface flow or, with the twist of a switch a good current along the aquarium base. A multi outlet water diffuser can be used instead to give a gentle water current that won't disturb baby fish or delicate plants or fish.
