HOW IT WORKS

The Fluval C Power Filter draws water from the aquarium through the
intake tube into the motor which then pumps water out of the impeller
assembly. The motor pushes the flow of unfiltered water through filter
inserts to trap particles, debris, and purify the water. The New Fluval C
series filtration system offers the ultimate multistage filtration available
in the market: With 2 x Mechanical, 1 x Chemical and 2 x Biological,
each stage operates independently.

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 (A) located on the top portion of the
frame. When fully visible (B), the mechanical Poly/Foam pad requires maintenance.

Stage 3: Chemical — Activated Carbon insert

Fluval Activated Carbon Filter Insert contains
100% premium research grade carbon.
Premium research grade carbon 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

RECYCLING

An additional hydraulic circuit conveys part of the intake water to the NEW innovative 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.

Sometimes delicate fish and plants require a gentler water flow. Fluval’s patented refiltration system

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.

with a damp cloth (never use harsh chemical products or detergents). Simple lemon juice may be useful for
removing calcareous encrustation. Rinse thoroughly afterward to eliminate acid residue. Following a routine
maintenance schedule will result in a healthier aquarium, and extend the life of the filter. Fluval C Power
Filters have been designed to facilitate these tasks, as they can be done within a matter of minutes.

bacteria to accelerate the maturation of new tanks.

Poly/Foam Pad

Remove mechanical frame from the filter body
and place in an empty bucket. Remove Poly/
Foam Pad from frame, and rinse using water
taken from the aquarium. Do not use tap

water as this will kill the beneficial bacteria
in your foam. NEVER use soap or detergents
as these products could be harmful to the
inhabitants of your aquarium. After rinsing,

reinstall the Poly/Foam Pad into the mechani­cal frame, then slide the frame into the rear
the of filter case with the cleaning indicator to
the right. Note: Make sure that the dense
polyester side is facing the grid on the frame.

For best results, replace every 4-6 weeks.

Activated Carbon Insert

Remove filter cover. Pull out
the chemical basket and
Trickle Chamber from filter
body. Separate the 2 sections,
then remove insert from
Chemical basket. Replace
with new insert. For best

results, replace every 2-4
weeks.

Bio-Screen

Remove filter cover. Using the tab, pull open the Trickle Chamber Cover and remove it. Place cover in the
sink or a bucket, and rinse with the Bio-Screen, using water taken from the aquarium. Do not use tap

water as this will kill the beneficial bacteria in your foam. For best results, replace every two to
three months.

Biological C-Nodes

Using the tab, pull open the Trickle Chamber Cover and remove it. Lightly rinse the C-Nodes with aquarium
water or replace 1/2 the quantity every 6 months. Never replace all the C-Nodes at one time, as the valuable
colonies of beneficial bacteria would be lost. For best results, completely fill the cartridge with additional
C- Nodes, but be sure to allow the cover to close easily.

Impeller and Motor

Unplug the power cord. Remove cover, filter baskets and discard water remaining in filter case. Remove motor
by twisting a 1/4 – turn gently in the direction of the arrow on the motor. Ease the motor down slowly to prevent
damage to the filter and motor guide. Pull impeller out of the impeller well, and rinse to remove accumulated
slime deposits. If the impeller well needs cleaning, scrub it gently with a Fluval Cleaning Brush (sold separately).
A cotton swab or impeller well brush (not supplied) can be used to remove more stubborn deposits. It is
recommended to wet motor seal ring to prevent damage before placing into filter case.

Note: It is recommended to replace the motor O-Ring on a yearly base to prevent leaking.

Re-position the magnetic impeller on the shaft and insert into the impeller well. Re-position the motor in the
filter case.

TROUBLE-SHOOTING & FAQs

Q. What if the power filter motor doesn’t start or makes a mechanical noise?

A. First check that all the filters’ components have been correctly installed. Then check to make sure

the impeller blades are free moving on magnet assembly.

Q. Why won’t the power filter motor re-start after performing filter insert maintenance?

A. Make sure the unit has been plugged back into the power outlet and that all parts are thoroughly

clean and replaced as directed. (See Power Filter Maintenance)

Q. What should I do if the priming process doesn’t occur?

A. Verify that:

• All parts are installed correctly

• Filter case is completely filled with water

• Unit is plugged into power outlet

• “U” tube is correctly installed

• The minimum water level inside the tank no more than 6 cm (2.25 inches) below the aquarium rim

Q. Why is the water cloudy in my new aquarium?

A. Bacterial cloudiness may occur during the first week of a new aquarium set-up and may last up to

six weeks. If the condition persists, consult your local aquarium professional.

Q. What happens if I forget to clean my filter inserts?

A. If the Power Filter is left unattended for too long, the filter inserts become clogged with debris.

The efficiency of the filtration is very low, and the filter inserts require immediate rinsing or
replacement. (See Filter Inserts Maintenance)

Q. When should I operate a reduced flow?

A. Reduced flow is most helpful during feeding times, or when the input suction or output stream is

too strong for small or delicate fish. (See How it Works — Patented Refiltration System.)

Q. Why should I use only aquarium water to rinse my filter inserts after they are installed?

A. Most cities add chlorine or other chemicals to eliminate harmful bacteria in drinking water for

human consumption. These additives, while harmless to us, are very toxic to fish.
