MAINTENANCE
WARNING: ALWAYS DISCONNECT ALL APPLIANCES IN THE AQUARIUM FROM THE ELECTRICAL SUPPLY
BEFORE PLACING HANDS IN THE WATER, BEFORE PUTTING ON OR TAKING OFF PARTS, AND WHENEVER
THE FILTER EQUIPMENT IS BEING INSTALLED, MAINTAINED OR HANDLED.
Media Care
Filter Media must be periodically replaced or cleaned in accordance with instructions on individual
packages. Actual life span of any type of media will vary based on usage and the specific
characteristics of each aquarium. To remove and replace media, follow the instructions below.
IMPORTANT: Never replace all media at the same time. Stagger filter media changes so that some
older media remains in use. This ensures re-seeding of beneficial bacteria, so that colonies discarded
with old media will be replaced by vigorous new ones. To enhance bacterial action, use Nutrafin
Cycle Biological Aquarium Supplement each time you change the media. All rubber parts; cover
gasket, primer stem, AquaStop Valve and seal rings should be periodically lubricated .
1. Drain the filter
1. Close the AquaStop valve by lifting the black lever all the way up. This seals off the input and
output hosing connections to maintain the vacuum that is necessary in order to restart the filter
without priming.
2. Unplug the power cord.
3. Lift the silver lock lever to release the AquaStop valve.
It is not necessary to remove the hosing from the AquaStop valve unless the hosing, the
AquaStop valve, or both require cleaning. (Periodic cleaning is recommended to ensure optimal
water flow. A good time to do this is during a major water change. To clean, rinse under
running tap water; if necessary use an appropriate Fluval Cleaning brush.)
4. Hold the unit by the canister, not the cover, and move it to an appropriate flat surface near a
sink or other drain. (Be sure to keep it upright to avoid spills.)
5. Release the lift-lock clamps; then push down on clamps to lift the cover/pump housing off the
canister and set it aside.
6. Holding the media cover in place, tilt the canister over the sink or drain, and pour out as much
water as possible.
7. Media and foam screen will be saturated with water. If your sink is not large enough to hold
them, have appropriate bucket nearby. Lift the foam screen, media cover, and media baskets
out of the canister and place them in your sink or bucket.
8. Rinse the interior of the canister with clear water. NEVER use soap or detergents when cleaning
canister or rinsing foam screen or media baskets. Traces of cleaning products may remain on
surfaces and damage sensitive fish tissues.
