Fluval U3 Underwater Filter 600 L/h, Aquariums up to 150L

Sitting neatly inside the tank, this underwater filter works through three stages, mechanical, chemical and biological, with BioMax rings handling the biological side to keep water clear and healthy. It suits freshwater, marine and reptile set-ups alike.

A flip-top lid means the cartridge can be reached in seconds, and the three-way flow control lets you match the current to your tank. Operation is quiet and energy-efficient, making it a tidy option for aquariums up to 150L.
