Maintenance
Changing/Cleaning HOB Water Polishing Unit
(Uses Large Aqueon
®
Filter Cartridge[s])
1. Remove lid from HOB Water Polishing Unit.
2. Pull cartridge and holster out of unit. Tilt sideways to allow water
to drain.
3. If not too dirty, cartridge and holster can be rinsed under tap
water to dislodge trapped dirt and debris.
4. If cartridge cannot be cleaned thoroughly or is more than 3 weeks old
it should be replaced with a new cartridge.
5. Insert cleaned/new cartridge into holster. Be sure the FRONT marking
on the cartridge is facing the holster and the notch in the bottom of
the cartridge and holster are aligned.
6. Insert the cleaned/new cartridge and holster back into the unit and
replace the cover.
7. Cartridge should be cleaned or replaced when water begins to bypass
over the top of the cartridge.
Changing/Cleaning Canister Media.
1. Unplug unit from power supply.
2. Close both the “IN” and “OUT” Quick Disconnect Valves. Separate
valves from Pump Head by unscrewing the Locking Rings.
3. Take filter to sink or outdoors for cleaning.
4. Tilt filter over to allow some water to drain out of the water inlets/
outlets. You don’t have to empty it completely.
5. Remove the media baskets one at a time. Dump out old activated
carbon in a garbage can.
6. Rinse the Bio-Ceramic Rings, the foam or any biological media to
remove trapped debris.
7. Replace carbon with or any other desired type of chemical filter media.
8. Reinsert baskets back into the canister. Be sure to align downdraft
holes with each basket.
Cleaning the Motor Unit and intake strainer.
1. Remove the impeller well cover.
2. Remove impeller and wipe down with a paper towel.
3. Replace impeller and impeller well cover.
4. Remove any debris trapped on the strainer by cleaning under
a tap or hose.
5. Thoroughly clean inside of impeller well to remove any buildup.
Excess build up can cause the motor to heat up.
Trouble Shooting
If Canister Filter does not prime...
1. Check to make sure that both Quick Disconnect Valves are open.
2. Check to make sure the downdraft holes in the filter baskets
are all aligned.
3. Check to make sure that all tubing connections are secure.
4. Check to make sure that all air is purged out of the lines according
to the priming instructions.
If Canister Filter is leaking...
1. Check to make sure all hose connections are locked on and tight.
2. Check to make sure the Vent Cap is in the locked position.
3. Check that there is not any dirt or debris between the top of the
canister body and the sealing gasket on the underside of the Pump
Head. Clean periodically and apply silicone grease to keep the gasket
supple and smooth.
4. Check to make sure the difference in height from the top of the
aquarium to the top of the canister filter is less than 6’. There is a
maximum amount of pressure that the canister clips and sealing
gasket can hold. If the differential between the canister top and top
of aquarium is too high, water will leak out of the sealing gasket
when the motor is shut off.
Helpful Hobbyist Hints:
1. There are many different ways and different media that can be used inside
a canister filter. None of these are wrong and often are entirely up to the
personal preference of the hobbyist. The recommended arrangement
described in these instructions places the coarsest media at the bottom
(upstream) of the canister with the media becoming finer and finer as you
move from upstream to downstream. The finest media is in the HOB
polisher which can be accessed and cleaned without shutting down the
canister. This arrangement traps the particulate debris in multiple layers
from largest to smallest. This is the most ideal way to reduce maintenance
on the canister and will function efficiently biologically and chemically as
any other method. Another popular method is to put the finest mechanical
media upstream (bottom) with the biological and chemical media
downstream. This will theoretically keep the biological and chemical media
from getting clogged with debris. However, this will also trap all debris on a
single layer vs. multiple layers and will require more frequent cleaning of
the canister.
2. Many hobbyists will recommend cleaning the media only in non-
chlorinated aquarium water vs. chlorinated tap water. There is nothing
wrong with this other than you lose water pressure which makes cleaning
more difficult. Cleaning the media with chlorinated tap water will kill off
some of the beneficial bacteria in the biological filter. However, the surfaces
within an established aquarium are so heavily colonized with beneficial
bacteria, that even a completely sterilized canister filter will recolonize with
beneficial bacteria within hours and any effect on water quality will be
negligible if at all.
3. If using a spray bar, it is important to keep the holes in the spray bar clean
to maximize water flow. Use a bottle or filter brush to periodically clean the
holes in the spray bar out. To provide the most dissolved oxygen in the
aquarium, the spray bar or outlet return should be placed near the water
surface so that water coming out of the canister can exchange gases at the
surface.
4. Flexible vinyl tubing becomes hard with time. Eventually the sections that
expand out over the hose barbs develop “memory” and may not seal
tightly again if removed from the hose barb. If necessary, the tubing may
need to be trimmed to remove the sections with memory and insert the
hose barbs into a new section without memory. Soaking the tubing in hot
water can soften it and make inserting the hose barbs into new and old
tubing easier.
