HOW IT WORKS
The AquaClear®Power Filter draws water from the aquarium
through an extension tube into the motor which then pumps
water out of the impeller assembly. The intake "U" tube
directs the flow of unfiltered water through filter inserts to
trap particles, debris, and purify the water.
CYCLEGUARD®MULTI-STAGE
FILTRATION SYSTEM
Provides optimal 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 recolonize, resulting in a stressful
environment. The AquaClear®multi-stage filtration system is different. Only one of three
filtration components is changed at a time. This ensures that significant amounts of
beneficial bacteria remain. There is never a sudden depletion of bacteria, so biological
filtration remains at highly effective levels.
Stage 1: Mechanical-Foam Filter Insert
AquaClear®Foam Filter Inserts perform mechanical filtration by
trapping particles and debris as they pass through the insert.
This unique foam, designed for use with AquaClear®Power
Filters, features optimal pore size for efficient mechanical and
biological filtration.
Stage 2: Chemical-Activated Carbon Filter Insert
AquaClear®Activated Carbon Filter Inserts contain 100%
premium research grade carbon. Premium research grade
carbon provides large amounts of surface area for adsorption of
undesirable impurities. The Activated Carbon Filter Inserts will
remove unwanted odors, discoloration and impurities resulting
in a crystal clear aquarium.
Stage 3: Biological-BioMax Insert
AquaClear®BioMax Filter Inserts contain BioMax ceramic rings.
The surface of BioMax is made up of a complex pore system that allows bacteria to thrive.
Use of the BioMax Filter Insert will provide optimal living space for beneficial bacteria and
enhance the removal of ammonia and nitrites resulting in a healthy aquarium environment.
NOTE: Regular replacement of AquaClear®Filter Inserts is essential for optimum filter
performance. PATENTED REFILTRATION SYSTEM
For a healthy aquarium and clear water
Sometimes delicate fish and plants require a gentler water flow. The patented AquaClear®
refiltration 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
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 for use during feeding, to ensure more
efficient food consumption and less waste.

POWER FILTER MAINTENANCE
Always unplug the Aquaclear®Power Filter prior to cleaning. Remove cover, filter basket,
and discard water remaining in the filter case. Thoroughly rinse collected debris from the
case, impeller cover and impeller assembly in 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 onto
aquarium.
(See Quick Start Guide 2, 3 and 4.)
Follow operating
instructions to restart and
prime Power Filter.
(See Power Filter Start-Up.)
Every three months, the
motor should be
thoroughly cleaned.
Remove cover, filter basket
and discard water
remaining in filter case.
Remove motor by twisting
a 1/4 -turn gently in the
direction of the arrow on
front. Ease motor down
slowly to prevent damage
to the filter and motor
guide.

TROUBLESHOOTING & FAQs
Q. What if the Power Filter motor doesn't start or makes a mechanical
noise?
A. Check to make sure 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 unit has been plugged back into 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. Verifiy that:
• all parts are installed correctly
• filter case is completely filled with water
• unit is plugged into power outlet
• ensure "U" tube lever is set to maximum position
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. In extreme cases, the filter basket may
be forced up from the filter case due to the pump pressure. This is
an indication that the efficiency of the filtration is very low and
that 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.
