CUSTOMER CARECUSTOMER CARE
Thank you for choosing this Aqua One product.
Your Aqua One product is covered for parts and labour for 1 year from the date of purchase as detailed in
the terms of the Guarantee in this instruction manual. For any inquiries or concerns regarding this product
or any of our products, please do not hesitate to contact your local Aqua One Retailer or visit Aqua One
Customer Care online in your country of purchase via the websites listed.
Regular maintenance of this product
and components are required in order
to keep equipment within guarantee
and to maintain sh health.
Before you work on
your aquarium, wash
your hands and arms.
It is very important to
remove dirt, moisturiser and
other impurities.
A new protein skimmer (or one
that has been thoroughly cleaned)
requires a running in period before
it reaches peak efciency. During
this time, it may spill microbubbles into the
sump and may under/overskim.
For this reason, your skimmer will require
daily inspection and adjustment. This is
commonly known as running in the skimmer.
This process typically takes 1-2 weeks.

SETTING UP
Carefully remove
skimmer from box
and remove all
packaging materials.
Check that all
assemblies have not
become dislodged
in transit and are in
place.
As with all aquarium
equipment, it is
recommended to
rinse the skimmer in
clean water before
installation.
Unpack and Prepare Skimmer
Ensure that the
Air Intake Hose is
securely connected
at both ends.
Please refer to previous pages for identication
and correct placement of skimmer components.
Positioning Skimmer
>1cm
20cm
15cm
Place the skimmer in the
appropriate location in your
sump. Hold it down and
allow it to ll with water.
Ensure that the venturi
intake is positioned more
than 1cm away from any
walls or obstructions in
the sump to avoid ow
restriction.
Optimum water level for
operation is 15-20cm. Try
to position the skimmer in
a spot where water level is
consistent.

For ease of waste collection, you
may wish to use a piece of airline*
tted to the Collection Cup Drain
and fed into a bottle. Be sure that
the airline is securely positioned.
Wait until after the running in period
before doing this.
Ensure that the Collection
Cup Drain Hose Plug is
securely closed by tightening
clockwise.
Setting Up
Ensure that your hands and all power cables are dry
before plugging in equipment and turning power on.
To control air ow into the
skimmer.
To adjust the water level in
the skimmer.
Adjusting Skimmer
Position the power cable so
that it does not interfere with
other equipment. Ensure
that you set up a Drip Loop
(see inset) and Important
Safeguards on Page 2.
Adjust the water level in the
skimmer to around half way
up the neck at rst. Further
adjustment may be required
as the skimmer is run in.

RUNNING IN
While running in the skimmer,
do not use a separate
collection bottle outside of the
sump as overskimming could
easily lead to ooding your
oor with skimmate.
Check levels daily and
adjust if required.
Running in the Skimmer
Because a completely
clean skimmer will require
running in again, it is
generally recommended
that overcleaning the body of the
skimmer be avoided.
The procedures shown on the
following pages are required to keep
the skimmer running efciently and
will not lead to the need to run in the
skimmer again.
NEVER clean any skimmer
components with detergents
or any other household
cleaning products. ONLY
use products designed for marine
aquarium use.
Adjusting for Desired Performance
When adjusting water level in skimmer, a higher water level will give you more liquid in the collection
cup (“Wet” skimming) while a lower water level will collect a dryer skimmate (“Dry” skimming)
Dry skimming.
Slower but less
water is lost.
Wet skimming.
Faster but more
water is lost.
A new protein skimmer (or one that has been thoroughly cleaned) requires a running in
period before it reaches peak efciency. During this time, it may spill microbubbles into
the sump and may under/overskim.
For this reason, your skimmer will require daily inspection and adjustment. This is
commonly known as running in the skimmer. This process typically takes 1-2 weeks.
Be aware that a new aquarium may have little to remove at rst. As the aquarium matures and
the skimmer is run in, it will begin to collect dissolved material in the collection cup (known as
“skimmate”).

Unplug all equipment
before beginning work on
any part of the aquarium.
MAINTENANCE
MONTHLY
Flush the venturi
intake to remove
any built up salts.
To do this without
disassembling, use
a clean syringe* to
push warm (NOT
hot!) fresh water
through the air intake
hose.
Ensure that you only
use water that is safe
for the aquarium.
Reverse Osmosis
water is ideal.
If Syringing doesn’t
When running at full
efciency, the body of
the skimmer should be
full of bubbles.
A good rule of thumb
for judging whether
there are enough
bubbles is to put your
hand behind the body
while the skimmer is
running.
Your hand should be
difcult to see (unless
there is light behind
which illuminates your
hand). If you can clearly
make out the details
behind the body, the
skimmer is not running
at full efciency.

clear a blockage, the
Venturi Intake will
need to be removed.
First, disconnect the
Air Intake Hose from
the Venturi Intake.
Unscrew the Venturi
Intake from the
Pump and remove.
Flush out the Venturi
Intake with clean tap
water.
If necessary, it can
be soaked in a
container of fresh
water or some white
vinegar overnight.
Do not soak the
o-ring in vinegar.
Rinse before
reinstalling in the
aquarium.
DAILY
Check and empty collection
cup or collection bottle (if
used) as required. Rinse as
required.
Check that the water level
in the skimmer is correct
and that there are lots of
bubbles in the body.
For extended life and ease of
assembly and disassembly during
maintenance, it is recommended
that o-rings are lubricated with
an aquarium safe o-ring lubricant such as
AquaLube*. Lubricating the o-rings will also
minimise the chance of parts
seizing leading to
accidental
breakages
during
maintenance.

MAINTENANCE CONT.
MONTHLY CONT.
Check that the Air Intake
Silencer and Air Intake Hose
don’t have any buildup of
minerals.
Rinse to ush out if required.
Parts may be soaked as
described for the Venturi
Intake on the previous page.
If you are using a
separate collection bottle,
ush out and inspect the
drain hose. Replace if
required.
Cleaning and
lubrication of o-rings
Rinse in fresh water
to remove any
particles attached.
Dry the o-ring.
Put a small amount
of lubricant* on and
smear it over the
o-ring so that it is
covered by a thin
lm.
To remove the o-ring, use a plastic card,
such as a credit card to gently lever the
o-ring up and over
the lip of its seat.
Then roll it off the
part.
2 MONTHS OR AS REQUIRED - PUMP MAINTENANCE
Remove the Collection Cup
Assembly, Water Level
Adjustment Knob, Air Intake
Silencer, Air Intake Hose
and Venturi Intake.
Turn the skimmer over and
carefully place it on a at
surface. Take care not to let
it fall over.
Remove the Adjuster Gear
Lock Nut.
*Sold Separately
Take care not to lose small parts when
servicing the skimmer, especially when
cleaning components at a sink.
