Engineered to create superior water quality, the Fluval C Power Filter provides extensive 5-stage filtration for outstanding results. The Power Filter is designed to provide maximum surface area and optimum dwell times in all stages of the filtration process. The result is clean, clear and healthy water for aquarium life to thrive in.
The Power Filter also features a patented re-filtration 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. The Power Filter’s completely modular design allows you to manage each stage separately and make changes at different times to maintain continuous biological activity. This results in a stress-free environment and ensures clear aquarium water.
New 5 Stage Filtration System
Unsurpassed Mechanical, Chemical, and Biological Filtration
A healthy aquarium requires “beneficial” bacteria. Invisible and harmless, beneficial bacteria are essential in the removal of toxic ammonia and nitrite. With cartridge filtration systems, when you throw away the cartridge, you throw away beneficial bacteria. It can take weeks for the bacteria to re-colonize, resulting in a stressful environment. The Fluval 5-stage filtration system is different. Only one of the filtration components is changed at a time. This ensures that the maximum amount of beneficial bacteria remains. There is never a sudden depletion of bacteria so biological filtration remains always at high effective levels.
Stage 1 & 2: Mechanical- Poly/Foam Pad
Effective mechanical filtration is essential for efficient chemical and biological filtration. The large surface area of the Poly/Foam pad effectively performs two stages of Mechanical filtration. The first stage of porous foam traps large particles and the second stage of dense polyester captures fine debris.
Note: The mechanical frame is equipped with a cleaning indicator located on the top portion of the frame. When fully visible the mechanical Poly/Foam pad requires maintenance.
Stage 3: Chemical- Activated Carbon Insert
The Fluval Activated Carbon Filter Insert contains 100% premium research grade carbon, which provides large amounts of surface area for adsorption of undesirable impurities. The activated carbon filter insert removes unwanted odors, discoloration and impurities, resulting in a crystal clear aquarium.
Stage 4: Biological-Bio-Screen
An additional hydraulic circuit conveys part of the intake water to the Bio-Screen placed at the top of the Trickle Chamber cover. Fluval’s Bio-Screen removes any debris before dripping into the biological chamber. It also ensures that the water pumped to the Trickle Chamber is evenly spread through all areas before it drips on the C-Nodes, which are contained in the chamber. The motion of water dropping slowly through the grids mimics the rain. This process ensures that additional oxygen is dissolved into the water before returning to the aquarium, for a more efficient biological filtration.
Stage 5: Biological- C-Nodes
The surface of the C-Nodes is made up of a complex pore system that provides optimal living space for beneficial bacteria to thrive and enhance the removal of ammonia and nitrites. The new “Star Shape” provides a higher filtration surface and more biological power than a traditional cartridge, resulting in a healthy aquarium environment.
Patented Refiltration System
For a healthy aquarium and clear water
Sometimes delicate fish and plants require a more gentle water flow. Fluvals’ patented re-filtration system allows you to control the flow rate without compromising filtration efficiency. When the flow rate is reduced, up to 50% of the water within the filter chamber is re-processed multiple times. More impurities are filtered out, creating a healthier tank with sparkling clean and clear water.
NOTE: A reduced flow rate is also recommended during feeding, to ensure more efficient food consumption and less waste.
The Fluval Power Filter C-Series consists of the C2, C3, and C4 models. The filters are suitable for both fresh and marine aquariums. Sizes available:
1.) Fluval C2 Power Filter, for 10 to 30 gallon aquariums; Maximum Flow Rate of 119 GPH

Alternate Filter Inserts
The following alternative chemical stage inserts are available (sold separately) as superior solutions to your filtration system.
Fluval Ammonia Remover Filter Insert
Ammonia remover is a natural ion-exchange media designed to remove toxic ammonia as water passes over it. Controlling ammonia levels reduces stress on fish. Use this to provide a healthy environment when setting up a new aquarium or maintaining one that contains a higher than average fish stock.
Fluval Zeo-Carb Filter Insert
Zeo-Carb filter insert is a blend of premium activated carbon and ammonia remover. It collectively eliminates impurities, odors and discoloration, while simultaneously removing toxic ammonia, resulting in a crystal clear and healthy aquarium. Water quality is the most important aspect of keeping fish. Maintaining the optimum water quality will help you keep your fish healthy and happy, and make the aquarium a beautiful and exciting addition to your home.
Power Filter Maintenance
For optimal performance it is recommended to clean the impeller cover assembly once a year. The motor should be thoroughly cleaned every three months. Always unplug the Fluval C Power Filter prior to cleaning. Remove cover, filter media and discard water remaining in the filter case. Thoroughly rinse collected debris from the case, impeller cover and impeller assembly using clear lukewarm water. The intake “U” tube and extension tube can be cleaned with a filter stem brush to remove any buildup of deposits. When all parts have been cleaned and thoroughly rinsed, reassemble filter and replace any scheduled media. Install the filter once again back on the aquarium making sure that the filter is tipped slightly forward. Then fill the Fluval C filter box with aquarium water. Finally plug the filter into an electrical outlet and the Fluval C Power Filter will self-prime and begin running in a few seconds.
