Proper filter maintenance begins with frequent visual inspections

to ensure normal operation and non-stressful conditions for fish.

Basic aquarium maintenance includes monthly 25% water changes
and gravel cleaning, as well as regular (once a month,

minimum

)

media replacement. Significantly reduced water flow (a sure
sign of clogging media), excessive mechanical or water noise,
cloudy and/or bad smelling water all require immediate attention.

NOTE: Water added to your aquarium should always be treated
(dechlorinated). Chlorine neutralizers are available at your
local pet outlet.

NEVER

submerge Filter Box in water.

NEVER

use soap, detergents or any non-recommended 
cleaning agents on or around filter.

ALWAYS

rinse parts with cold water after cleaning.

ALWAYS

unplug Penguin Power Filter before 
performing maintenance.

We recommend the following complete maintenance procedure 
for the BIO-Wheel Power Filter as needed (at least every month):

Before you begin, unplug your Penguin Power Filter.

NOTE: Bearings can fall off axle. Before
cleaning, remove bearings and put
them aside. For your convenience,
we have included two spare Bearings
located on the underside of the 

Filter

Box Cover

(Fig. 7)

IMPORTANT: The BIO-Wheel should not be tampered with 
or disassembled. Discoloration of pleated BIO-Wheel material 
is normal and desirable. NEVER CLEAN THE BIO-WHEEL.
If the BIO-Wheel becomes so heavily cultured that it no
longer rotates, you can gently rinse the surface in order to
remove the heaviest buildup. Use treated (dechorinated), room
temperature tap water only. As long as a BIO-Wheel is not
damaged, it does not need to be replaced.

1. Remove Cover.

2. Carefully remove BIO-Wheel and Bracket. If calcium deposit 

buildup around Bearings and Brackets interferes with rotation,
carefully remove BIO-Wheel from Bracket and gently brush 
bearing and axle area clean.To avoid disturbing beneficial bacteria 
culture, handle a BIO-Wheel by the End Caps and/or Axle.
Any algae, mineral or other buildup that hinder rotation can 
be eliminated with a gentle rinse in room temperature water.

3. Set BIO-Wheel and Bracket aside.

4. Remove and discard used Rite-Size Cartridge(s).

MODEL 330 ONLY   

Remove 

BIO-Baskets.

Replace media.

5. Remove 

Intake Tube

and clean 

inside with a flexible filter brush 
(Fig. 8).We recommend the 

Marineland Flexi-Brush -

available at your aquarium store.

6. Lift Filter Box from back
