Fluval C3 Power Filter for aquariums between 20 to 50 gallons

The Fluval C3 Power Filter features 5 stages of filtration: 2 mechanical, 1 chemical and 2 biological stages for top performance. The C3 Power Filter is equipped with the Fluval C3 Poly/Foam, Activated Carbon, C-nodes and Bio-Screen pad. An integrated trickle chamber filled with C-Nodes is where biological filtration is super charged for fast and efficient nitrification. The mechanical filtration is performed by a dual layer of foam and polyester, and is easily removed for quick cleaning. The patented recirculation grid enhances mechanical filtration when the flow rate is reduced. A convenient chemical insert basket directs water flow to maximize toxin removal. Maintaining only one stage at a time will preserve beneficial bacteria, resulting in a stress-free environment, while ensuring aquarium water stays clear. The Fluval C3 Power Filter clips on, and is ideal for use on aquariums up to thirty gallons. It is the perfect way to provide your fish with refreshing and clear water
