Fluval C2 Power Filter - 5 Stage Filtration

The Power Filter is designed to provide maximum surface area and optimum dwell times in all stages of the filtration process. Rigorous 2-stage mechanical filtration is performed by a thick layer of poly/foam that effectively traps large and fine debris. The foam slides out easily for quick cleaning. Activated carbon, located in an easily-manageable and removable basket, performs thorough chemical filtration and effectively removes toxins.In the final two stages, a 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.The result is clean, clear and healthy water for aquarium life to thrive in.
