Fluval U4 internal filter 130-240l

The 3-step filtration with BIOMAX ensures excellent water quality in the aquarium, while the "flip top" access ensures quick and easy filter replacement. This, and the 3 way flow control means the new FLUVAL U series is a milestone in internal filtering. 3-phase filtration: The new 3-phase inner filters from FLUVAL are ideal for use in freshwater and seawater aquariums as well as in terrariums.
The foam in phase 1 removes large particles of dirt.
The polyester/activated charcoal filter cartridge in phase 2 captures small particles, improves water purity and removes impurities. BIOMAX in phase 3 provides optimal, biological filter efficiency

Ideal as a stand-alone solution, supplementary filter, or anywhere where an external filter insert is not possible
