E. To avoid the possibility of the appliance plug or
receptacle getting wet, position the appliance to one
side of a wall mounted receptacle to prevent water
from dripping onto the receptacle or plug. A “drip
loop” (see illustration 1) should be arranged by the
user for the cord connecting appliance to a
receptacle. The “drip loop” is that part of the cord
below the level of the receptacle or the connector if
an extension cord is used, to prevent water traveling
along the cord and coming in contact with the
receptacle.
If the plug or receptacle
does get wet, DON’T
unplug the cord. Disconnect
the fuse or circuit breaker
that supplies power to the

may result in damage to this product.
IMPORTANT SAFETY INSTRUCTIONS
WARNING - To guard against injury, basic safety precautions should be observed.
READ AND FOLLOW ALL SAFETY INSTRUCTIONS
To guard against injury, basic safety precautions should be observed
when handling the Fluval Canister Filter, including the following:

The FX-5 filter siphons water and suspended
debris in through its clog-proof intake strainer,
then sends it through three levels of foam,
which traps most particulate matter. The
powerful pump then sends it through the
multiple levels of media for whatever cleaning
and processing sequence you have chosen.
As water flows back into the aquarium, the
flared design of the adjustable output nozzle
disperses it in multiple directions, agitating the
water and creating currents that help break
down wastes, and prevent them from settling.
All for a continuous flow of pure, precisely
treated water.
The Fluval Canister Filter offers unparalleled
filtration power, maximum versatility and
incredible control in fine-tuning water
characteristics. Our multi-stage system allows
you to stack filtration media in the precise
combination of layers that will work best for
your aquarium. Thus providing you infinite
flexibility in creating and maintaining the ideal
environment for your fish.
Its massive capacity and powerful integrated
motor processes and recirculates fully 607 US
gallons (2300 liters) of water every hour,
enabling you to precisely manage water
conditions for aquariums as large as 400 US
gallons (1500 liters). It will hold up to 1.5 gallons
(5.9 liters) of media, yet it’scompact enough to
fit under almost any aquarium cabinet.
With Fluval’s unique Smart-Pump Technology,
this self-priming system offers plug-in-and-start
convenience. Upon start-up the canister fills
with water, pauses to evacuate air, immediately
begins the filtering process, and continues
filtering until it is unplugged. Once every 24
hours, the filter will pause again to evacuate
any air that has become trapped in the
system–to maintain the total vacuum necessary
for maximum efficiency.
The FX5’s stack of media baskets allow multiple
options to modify water with scientific
precision. Use one type of media in each basket,
or layer two or three types to suit your
aquarium’s needs.
The FX5 Filter also offers incomparable ease-of-
use features: click-fit connections you just push
on; AquaStop valves so you can handle routine
maintenance without breaking the system’s
vacuum, no need to disassemble hosing;
innovative handles that let you lift the entire
stack of baskets out to change or clean media;
and a purge valve and extra Aquastop Valve so
you can empty the canister easily,no need to
move or lift a heavy, water-laden tank.
This filter’ssuperior performance and capability
arebacked by Fluval’swell-earned reputation
for the best in fish and aquarium care. HARS
(Hagen Aquatic Research Station) certification is
your assurance of the most up-to-date and
reliable research in aqua-care science.
For complete understanding of your Fluval
Multi-Stage Canister Filter, and enjoyment of all
its capabilities, please read and follow these
instructions for proper installation, maintenance,
and use. Failureto do so may result in loss of
fish life and/or damage to the filter. SAVE THESE
INSTRUCTIONS FOR FUTURE REFERENCE.
HIGH PERFORMANCE CANISTER FILTER
SYSTEM OVERVIEW
EN-2

FLUVAL STATE-OF-THE ART TECHNOLOGY
AquaStop Valves
The AquaStop valve makes maintenance easy by allowing you to
stop the water flow with an easy 90-degree turn of the valve
lever. This means you can separate the hosing from the filter in
one step. The valve lever can also be used to regulate water flow
with no harm to the motor or its components. Three Valves are
provided; one for the intake, one for the output and one to be
used to drain the filter under certain circumstances during the
maintenance process.
Click-fit Connectors
Click-fit connectors are designed for quick set-up and leak-proof
maintenance. You just push the intake and output assemblies
(Aquastop valves and attached hosing) down. Once you hear the
“click,” you know the connection is secure and watertight.
Lift-Out Stack of Media Baskets
The lift-out stack of media baskets is at the heart of Fluval multi-
stage filtration. These large capacity baskets enable you to stack
filtration media in the precise combination of layers that will
work best for your aquarium. Each basket is lined with a foam
insert for effective mechanical pre-filtering. The instant-release
T-handles let you lift, then separate the basket stack quickly and
easily, making routine maintenance simple.
High Capacity Canister
The FX5’scompact, super capacity tank processes and recirculates
fully 607 US gallons (2300 liters) of water every hour and
accommodates the stack of media baskets with their capacity
of up to 1.5 gallons (5.9 liters) of media. Yet this enormous-
capacity tank is short enough (21 in./54cm) to fit under most
large aquariums.

EN-4
Smart-Pump Technology
Designed and engineered for reliable filtration of delicately
balanced aquarium environments, Fluval’s FX5 SMART PUMP
technology employs an electronic circuit board to continually
monitor the pump. Impeller speed and force are constantly
measured to ensure powerful output and energy efficiency.
Smart pump technology is also critical in evacuating any air that
may build up in the system. Once every 24 hours, the filter will
pause and allow any trapped air to escape, thus maintaining
maximum filtration efficiency.
Self-Priming Instant-Start System
With the FX5, there’s never any need for manual siphoning. As
soon as you plug the filter in, the canister fills with water from
your aquarium. It pumps for 2 minutes, pauses for 2 minutes to
evacuate air from the system, then immediately begins the
filtering process.
Purge Valve
The FX5 canister features a purge valve drain at its base.
This makes it possible for you to empty the canister for
maintenance beforemoving it.
Clog-Proof Intake Strainer
The wide, rounded mouth of the FX5 intake strainer is shaped to
siphon water quickly.Covered by a fine screen that’s beveled to
repel debris, it is virtually clog-proof, so there is never a build-up
of solids that could impede water flow.
Multi-Directional Output Nozzle
The flared spout of the adjustable output nozzle sends multiple
streams of purified water towardall corners of the aquarium,
creating currents that agitate the water to break down wastes
and help hold them in suspension until they can be drawn into
the filter by the intake strainer.With more waste solids kept
afloat, fewer settle, which means that bottom surfaces, and in
fact the entire aquarium, is kept cleaner.

INSTALLATION AND USE
IMPORTANT: Read all instructions before beginning.
•For best results, top off water in aquarium before beginning setup.
•Allow 45-60 minutes for setup and installation.
•Tools required: Phillips screwdriver and utility knife.
(NOTE: For an unusually shallow aquarium, the intake tube may
need to be cut; this requires a hacksaw.)
DO NOT PLUG IN FILTER UNTIL SETUP IS COMPLETE AND UNIT IS FILLED WITH WATER.
1. Unpack and identify all parts
Use the diagram on the inside front cover as a guide.
2. Prepare the aquarium
1. Decide on filter placement. Remember,this is a gravity-fed
system. For it to work properly,all the Installation
Requirements below must be adhered to.
Installation Requirements
•For best results fill aquarium to maximum level
before beginning setup.
•The filter lid must be at least 7.8 in. (20cm) below your
aquarium’s water level but never more than 4.9 ft. (150cm).
•The hosing supplied with the unit is 9.8 ft. (3m) long.
If longer hosing is required, intake hosing must
NOT exceed 9.8 ft. (3m) and the total length of
intake and outlet hosing combined must not
exceed 16.4 ft. (5m).
•Hosing must follow a straight path from the filter to the
aquarium rim, with some slack, but no loops.
•The water level should never be more than 7.8 in.
(20 cm)below your aquarium rim.
•NEVER install the filter above the water level.
•For best performance, the filter should be completely
beneath the aquarium.
•Position Purge Valve so that you will be able to attach a
hose without moving the unit.

2. Place the two rim connectors over the back top edge of the aquarium. Place one just above
the spot where you want to place the intake tube; place the other just over the spot where
you want to position the output nozzle. Be sure that the long end of the bracket is on the
inside of the aquarium.
The rubber rings on the connectors are designed to help them adhere to tank glass better.
If the aquarium walls are thinner than 5/8” (1.58 cm) replace the rubber ring with the four
smaller suction cups provided.
Important: Be sure to position the intake tube away from any air source—an air stone, an
aeration device, protein skimmer or the output valve. Air entering the intake strainer will
diminish filter efficiency.
INSTALLATION AND USE
Note: A dropped ledge rim requires purchase
of an extra rim connector. (See “Replace-
ment Parts” for ordering information.)

3. Prepare intake connections
1. Connect the hosing to one of the three valves:
a. Loosen one of the metal clamps, and slide it onto one
end of the hosing.
b. Push the end of the hosing onto the valve; push it all
the way, as far as it will go.
c. Position the metal clamp over the rubber connector,
and tighten.
2. Measure and cut the hosing. You will need a length of
hosing that reaches comfortably from inside the aquarium
to the filter canister.
Important: Hosing should follow a straight path from the
filter to the aquarium rim, with some slack, but no loops.
If the hosing is too long, the filter will not work efficiently.
a. Place the valve end of the hosing at the approximate
spot whereit will be positioned on the filter lid
(once the filter is installed).
b. Stretch out the hosing so it rests over the “intake”
rim bracket.
c. At a spot at least 6 in. (15cm) beyond the aquarium rim,
use a utility knife to cut the hosing.Do not cut it too
short. Remember,you can always cut it shorter during
final installation, if necessary.
3. Push the cut end of this “intake” hosing into the rubber
connector on the intake tube. Push the hosing in by at least
1in. (2.5cm) without twisting it.
4. Place the intake strainer in the tank, making sure it is at
least 3 in. (7.5 cm) from the bottom. (If the tube is too long
for the height of your aquarium, remove the strainer,cut the
intake tube with a hacksaw, and then replace the strainer.)
Once the intake strainer is properly positioned, lock it in
place by pressing the suction cups against the glass.
5. Fasten the intake strainer’s hosing onto the rim connector
using the three rim connector clips.

4. Prepare output connections
1. Connect the hosing to the second valve
(just as for the intake hosing):
a. Loosen the second metal clamp, and slide it onto the
factory-finished end of the hosing (not the cut end).
b. Push the end of the hosing onto the valve; push it all
the way, as far as it will go.
c. Position the metal clamp over the rubber connector,
and tighten.
2. Measure and cut the hosing. Again, you will need a length
of hosing that reaches comfortably from inside the
aquarium to the filter canister.
Reminder: Hosing should follow a straight path from the
filter to the aquarium rim, with some slack, but no loops.
If the hose is too long, the filter will not work efficiently.
a. Place the valve end of the hosing at the approximate
spot where it will be positioned on the filter lid
(once the filter is installed).
b. Stretch out the hosing so it rests over the “output”
rim bracket.
c. At a spot at least 6 in. (15 cm) beyond the aquarium rim,
use a utility knife to cut the hosing. Do not cut it too
short. Remember, you can always cut it shorter during
final installation, if necessary
3. Push the cut end of this “output” hosing into the rubber
connector of the output nozzle. Push the hosing in by at
least 1 in. (2.5cm) without twisting it.
4. Place the nozzle in the tank about 1 in. (2.5cm)
below the water line.
5. Fasten the hosing to the “output” bracket using
the three rim connector clips.

Media Basket
>0.5 in. (1 cm)
4. Rinse the media baskets and foam inserts under running
tap water to remove any dust particles.
5. Replace the foam inserts, and fill the center of each
basket with filtering media (Media not included. See
“About Media” for detailed descriptions of all media
available from Fluval).Leave at least 0.5 in. (1cm) free space
on top of the media, so the baskets will fit together properly.
6. Stack the baskets, carefully aligning them, so that all
shapes match. Reinsertthe T-handles into their vertical
slots, and replace the baskets in the filter canister. The
foam in the upper basket should be just about even with
the top edge of the canister (the output tube, which is
affixed to the inside of the canister, will be protruding
slightly).

EN-10
7. Move the filter canister to its final position.
8. Be certain the purge valve is in the vertical
(closed) position.
9. Pour about 2 gallons (8 liters) of water into the
filter canister.
IMPORTANT: Correct water volume is necessary
for system priming.
10. Place the filter lid back on the canister. Check to
make sure the filter lid seal ring is present and
installed properly on the canister lid. There is
only one orientation possible. Gently press the
lid down until the output tube is firmly seated in
the OUT connection on the filter lid.
Important: If the inlet tube attached to the
canister lid has slipped out of its seat, be sure to
fully re-insertit under the IN connection of the lid.
11. Replace and hand-tighten the eight lid fasteners.
The lid is properly closed when it is in direct
contact with the canister.DO NOT USE ANY
TOOLS, AS DOING SO MAYDAMAGE THE UNIT.

INSTALLATION AND USE
6. Install the filter
1. Once the filter unit is in its final position, make sure that the aquarium has the appropriate
amount of water.
Important Reminders:
•The filter lid must be at least 7.8 in. (20 cm) below your aquarium’s water level but never more
than 4.9 ft. (150 cm).
•The hosing supplied with the unit is 9.8 ft. (3m) long. If longer hosing is required, intake
hosing must not exceed 9.8 ft. (3m) and the total length of intake and outlet hosing
combined must not exceed 16.4 ft. (5m).
•Hosing must follow a straight path from the filter to the aquarium rim, with some slack,
but no loops.
•For the self priming featureto work properly the water level cannot be morethan 7.8 in.
(20 cm) below your aquarium rim.
•NEVER install the filter above the water level.
•For best performance, the filter should be completely beneath the aquarium.
•Position purge valve so that you will be able to attach a hose without moving the unit.
•Important: Check to be sure that the hosing follows a straight path from the aquarium rim
to the filter.Leave some slack, but no loops. If the hosing is too long, the filter will not
work efficiently.
•Assure the lid seal ring is already installed on the filter canister lid.
2. Grasp the intake valve (which is at the end of the hosing
attached to the intake tube);slide it onto the IN connection
on the filter lid, and press until it clicks into place.
3. Grasp the output valve (which is at the end of the hosing
attached to the output nozzle);slide it onto the OUT

INSTALLATION AND USE
7. Start the Filter
1. Check your installation.
Before turning the filter on, be sure that:
a. The purge valve is in the closed (vertical) position,and its
rubber cap is secured in place by the lock nut.
b. All top lid fasteners are well tightened.
c. The IN and OUT valves are fully open
(valve levers should be vertical).
d. The intake strainer is fully submersed in water.
e. There are 2gallons (8 liters) of water in the canister.
VERYIMPORTANT:You need to know that as soon as the unit
is plugged in, it will start, and will immediately go through its
automatic priming sequence.
2. Plug the unit into an electrical outlet.
The electronic automatic priming sequence will begin.
This is what will happen:
a. The pump will run for 2 minutes to fill the filter canister
with aquarium water.
b. The pump will stop for 2 minutes to evacuate air from
the filter canister.
c. The pump will start again; it will remain on and will run
continuously until it is unplugged.
This sequence will repeat itself every time the unit is
unplugged and plugged back in.
Approximately every 24 hours: The pump will stop for
2minutes to evacuate any air that may have become
trapped inside the unit.

There are three basic types of filtration. Mechanical
filter media removes waste particles and solid debris
through mechanical strainers. Biological filter media
breaks down and eliminate organic toxins—ammonia
and nitrite—through bacterial action. And chemical
filter media actively changes water characteristics
through deliberately managed chemical reactions.
Fluval offers a wide variety of filter media materials.
Some perform more than one job. This is the true
power of the Fluval system—the broad range of
media available for use in its baskets. These extensive
choices give you maximum flexibility in designing the
aquatic environment just right for your aquarium.
The Fluval Stack of Media Baskets
The stack of three large-capacity
media baskets in the Fluval FX5 Filter
enables you to employ all three types
of filtration, in whatever
configuration or sequence you
determine. Filtration always begins
with a mechanical stage of waste
particle removal as water is drawn
through the foam that lines the
perimeter of each basket. It continues
as water is pumped down through
the media in the three baskets. In all,
the media baskets will hold a total of
1.5 gallons (5.9 liters) of media.
Because you can place one, two, or
even three different kinds of media in each basket,
you will be able to design a system that provides
additional mechanical filtration, as well as biological
and chemical filtration in the widest possible variety
of combinations. This section contains detailed
information, as well as general guidelines, about
media selection and use.
❶Top Media Basket
Pre-Filter, Carbon,and Zeo-Carb are all options for
screening small particles from the water. Pre-Filter is
inert, acting solely to create a screen. Carbon removes
dyes, medications, and solubilized wastes that a simple
screen cannot. Zeo-Carb removes ammonia; it is often
used in beginning setups to keep initial ammonia
spikes lower than would occur naturally.
❷Middle Media Basket
The middle media basket is useful for chemically
modifying water. Peat Granules,for example will
gradually lower the water’s pH level.
The middle chamber is a good place to begin the
biological reduction process as well. Many media
types provide both mechanical filtering and
biological treatment, creating an excellent
environment for beneficial bacteria to proliferate.
Even many chemical compounds will support colonies
of bacteria. With the primary mechanical purification
of the water stream occurring in the foam inserts, it
is typical to load additional biological
media into the middle media basket.
BioMax and extra Carbon or
Ammonia Remover are commonly
used. This is also the place where
more exotic media, chosen for a
specific application, can be used.
❸Bottom Media Basket
This basket receives the purest water
stream, making it the proper place
for dedicated biological media.
Placed here, BioMax,for example,
provides optimal biological power in
avery compact ring. With a multitude
of pores perforating both the surface
and the internal matrix, it is an ideal
substrate for this position. Tocapture
any small particles remaining in the water before it
reaches this final stage of filtration, consider layering
aPolishing Pad, a fine mechanical filter, on top of
any biological or chemical media placed in the
bottom basket. This will prevent the clogging of the
delicate pores of the media used here, enhancing its
useful life.
Tobe effective, media must be cleaned or replaced
regularly. Check media monthly, and change when
necessary. However,never change all media at
the same time, or valuable bacterial colonies
will be lost.

Fluval Carbon—a premium, research grade, low-ash carbon—improves water clarity and
color, while also removing odors. Highly porous, it provides large amounts of surface
area for adsorption of impurities. It effectively removes heavy metals, odors,
discolorations, organic contaminants, and pollutants to leave your aquarium water
crystal clear and sparkling. This product does not release phosphates. Carbon loses its
activity without outward sign. Replace monthly to ensure that active adsorption is
maintained. Carbon should always be removed when medication is being administered
in aquarium water. Also, because carbon will adsorb a large percentage of the nutrients
in plant fertilizer products, it should be used carefully when keeping live plants.
