Product Description

Introducing the Fluval C4 Hang On Aquarium Filter. This product is engineered to create superior water quality, providing extensive 5-stage filtration – 2 mechanical, 1 chemical and 2 biological stages – the result is clean, clear and healthy water for aquarium life to thrive in. It also features a patented refiltration control system that lets you slow down the water output, creating a gentle flow to protect delicate fish and plants. At the same, a slower water circulation increases water dwell time in the filter, resulting in cleaner aquarium water.

Key Features & Benefits:

  • Extensive 5-stage filter produces clean, clear and healthy water for aquarium life to thrive.
  • Rigorous 2-stage mechanical filtration is performed by a thick layer of poly/foam that effectively traps large and fine debris.
  • Activated carbon, located in an easily-manageable and removable basket, performs thorough chemical filtration and effectively removes toxins.
  • Bio-Screen pad provides massive biological surface area for friendly bacteria to colonize, plus it blocks debris from entering a trickle chamber filled with C-Nodes that are super-charged for fast and efficient nitrification.
  • Completely modular design allows you to manage each stage separately and make changes at different times to maintain continuous biological activity for a stress-free environment.
  • Comes complete with a Poly/Foam, Activated Carbon, C-Nodes and Bio-Screen Pad.
