1. Commissioning (putting into operation)
Please take the Bubble King®out of the package and
check the skimmer for shipping damage, which must be
led to your local dealer within 24 hours.
The Bubble King®is pre-installed and ready for operation
and may be put into the lter sump for instant operation
(only internal). Please install the skimmer head and put
the skimmer into the lter sump or equivalent to get famil-
iar to the device.
The lower water level of the Bubble King®should
not be below 15 cm and shouldn’t exceed 30 cm.
The best matching water level is between 20 and 25 cm.
Under some circumstances the water level may be above
30 cm but this will prevent adjusting of the foam level.
Now, please plug the power cable into the desired wall out-
let. Please note, that sub water level pumps must be only
connected to a ground fault circuit interrupter (FI safety
switch). Furthermore we recommend a frame connector
with voltage surge protection, which, in the case of a short
circuit in the mains, prevents a high voltage boost to the
Red Dragon®pump which will burn the internal fuse. In the
case the RD fuse (melting fuse) was blown, the motor can’t
be repaired and therefore must be replaced.
Please note that it is absolutely prohibited to cut the plug
from the power cable to prolong or short the power line.
Sub water pumps with cut power cables do not meet the
safety regulations and any warranty on the device will be
void. Furthermore, we are not allowed to repair sub water
pumps, if the power cable
was manipulated.
After running the pump, within a short time, a foam cush-
ion should be formed like shown on the right gure above.
Let the skimmer run for several hours without placing the
pot on top.
In general, new skimmers require
a certain amount
of time to produce rm foam.
New skimmers may contain several substances like
grease, glue residue and similar substances which pre-
vent foam forming. Depending on the contamination of
your aquarium water it may take from 2 minutes to 1 week
until solid foam was formed.
A proper prediction when your skimmer was run in can’t
be made.
If the skimmer doesn’t produce solid bubbles this is due
to a normal degreasing process which can’t be shortened.
Shown in the gure below.
During this process, move
the telescope tube to the
lowest level, which is the
stop of the tube holder.
This will prevent instant
overow while the
skimmer performs its
initial operation.

If the foam was solid enough
adjust the water level in
the skimmer by lifting the
telescope tube. There is
a small screw on the side
of the wedge shaped tube
to secure the tube into its
holder. Please never use a
tool and do not overtighten
the screw. Please note that
the telescope tube can’t be
100 % waterproof.
Before installing the skimmer head, make sure the inter-
nal, red O-ring was perfectly seated without ripples or simi-
lar irregularities. These may lead into leakage.
On the gure above (Current water level) you can see
the water level stripline approx. 5 cm below the maximum
level. This water level stripline can be lowered or rised by
turning the tube. The water level stripline is different in ev-
ery aquarium, depending on quality and surface tension of
the salt water.
The water level should be within the cone and the lower
end of the skimmer head. This line ensures a dry foaming.
Our recommendation is a guideline not a must, and thus,
the line may be exceeded in some cases. It behoves to the
user to decide whether he prefers wet or dry foam.
The Bubble King®water drain:
Originally the drain tubing of the Bubble King® is not xed
by gluing. We do not recommend any gluing of the tubes.
The tubes can be set into any direction, but we do not
recommend putting the water drain into the environment
of the pump inlet, because this will provide treated water
to the pump, which will drastically decrease the perfor-
mance. Basically the lter should be designed to provide
high water ow through to the skimmer.
All Bubble King®DeLuxe models have an integrated drain
on the skimmer head (see right g. above). The drain al-
lows you to remove and clean the skimmer head and drain
the foam residue (adsorbate).
The drain tubing had been sealed factory side by a cone
shaped silicone plug. On the client side the drain may be
prolonged by a hose or tubes to feed the adsorbate into a
tank, into a bucket or directly into the sewer. We recom-
mend keeping the adsorbate drain permanently closed.
Notice:
Please do not wait too long until cleaning an over-lled pot.
By problems caused by low water level:
The pump inlet must not cause a swirl like shown on the
g. on the left below, to prevent permanent damage to the
pump. Please do not use a 90 degrees angular tube, but
a 90 degrees arch. Due to the deection angles are reduc-
ing the performance more than 50 % compared to an arch.
The nozzle has been trimmed to 40.0 mm to allow easy
installation of an arch.
1.1. Setting the adjustable nozzle, only internal skimmers
All internal Bubble King® skimmers are t with an adjust-
able water inlet nozzle. Using the nozzle mainly adjusts
the water ow rarely affecting the air performance.
Please note:
A skimmer performs best, when a perfectly well dened
amount of water and air enters the skimmer on the lowest
point of the device. The Bubble King®Red Dragon®pumps

has a so called “ideal operation point“. The ideal point is
well dened and will be found as shown below:
Please turn to completely screw nozzle, as on the upper
left picture shown. Then please turn to the nozzle to the
left, counter clockwise.
Usually 1 - 1½ turn. This is the best operating point.
The black dots are used only for orientation.
The user may exceed or under-run this point as desired.
Under-running the point may be advisable to reduce the
skimmer performance in coral tanks with only a few sh. In-
creasing the ow-through may be advisable on tanks with
many sh or in the case of disaster. A dying big Tridacna,
algae emitting spores or poisoning triggered by dying ani-
mals or similar reasons require a fast and wet foaming.
Notice:
Each spin increases water ow-through by
approx. 500 liters. Operation without nozzle screw is
prohibited. The air ow would be reduced by half and
water ow would be increased by 300%. In this state
the pump will be overloaded and within a short time
automatically switched off. The noise level also would
exceed dramatically.
1.2. Regulating the water level stripline in the skimmer
cup by the torque tube, internal and external skimmer
It is also possible to adjust the water level in the skimmer
by help of the wedge shaped tube. Basically we recom-
mend to set the water level with the telescope tube.
The wedge shaped tube should be only used for ne tun-
ing or ooding of the skimmer head. In this case ooding
means the cleaning of the Bubble King®head without re-
moving the head.
The wedge shaped tube must be almost closed forcing the
water level immediately into the skimmer head. Now use
a brush to clean the riser tube to ush the residue into the
skimmer head without draining back into the lter tank.
The O-ring shown on the left upper gure should be lubri-
cated by silicone oil from time to time to keep spinning of
the wedge shaped tube easy.
The O-ring also prevents salt and water drain from the T-
set, which would complicate spinning the tube.
The position of the wedge shaped tube is shown by two
black dots. If both dots are aligned, like shown on the right
gure, the wedge shaped tube is opened 100 %.
Spinning the tube to the left
or to the right like shown on
the gure will ne tune the
foam level.

1.3. Installation and connection of the external skimmer
The external Bubble King®DeLuxe skimmer functions
exactly like the internal one. Unless otherwise stated, all
instructions listed in the handbook for internal skimmers
also apply for external skimmers.
However, there is great difference in terms of the connec-
tion because the external Bubble King®DeLuxe skimmer
requires a delivery pump which supplies the skimmer and
the skimmer pump with the water to be ltered. Please re-
fer to the data specication of your external skimmer for
information regarding the power of the delivery pump.
It is also important to note that the external skimmer should
be positioned no lower or higher than the lter unit or water
level. (See left sketch below)
Note: If possible, the water sucked in by the delivery
pump should be roughly ltered ahead to avoid
unnecessarily polluting or contaminating the delivery
and skimmer pumps with snail shells or pieces of coral
for example, which could wear the pin wheel or impeller
and/or lead to a defect.

2. Maintenance
We recommend the cleaning of the Bubble King®DeLuxe
at frequent intervals respectively to check the needle
wheel for foreign objects. To check the needle wheel it is
not necessary to remove the internal skimmer from the
lter tank.
Unplug the skimmer from the mains. Remove the jet tube
from its seating. Turn the skimmer into your direction and
optically check the rst row of needles for foreign objects
like snails, mussels, activated carbon pellets, lter cotton
or food debris. In case of an accumulation of debris in the
pump, the pump must be disassembled.
Red Dragon®Bubble King®pumps have a built-in automat-
ic shutoff. The internal circuit is permanently measuring
the pumps power consumption. In the case of serious cal-
cifying, and thus, stiff bearings, the internal circuit will clas-
sify the rising power consumption as a failure and switch
off the pump, due to safety reasons. Because of this be-
haviour a Bubble King®pump never can be damaged by
smouldering re or other damage due to a short circuit.
Just plug off and on to bring the pump back into operation.
Please note, that it is not advisable to trick the internal
circuit into normal operation by a repeated switching of the
device. If a Red Dragon®pump was switched off, a failure
occurred apparently, which must be solved. If happened,
usually only a cleaning session is required.
IMPORTANT:
Permanently tricking the circuit may result in
severe motor damage, which will not be
covered by warranty.
2.1. Disassembling the pump
After removing the pump from the silicone hose please
remove the inlet nozzle from the designated opening. Put
the skimmer onto a at, soft surface or a towel and start to
disassemble the pump as shown below.
You just need a standard mid size screw driver and an
Allen wrench M5 required for a complete disassembling.
Turn off the 4 housing screws and remove the head.
Caution:Thepumpholdersaremadefromplastic.Justtighten
the screws until the gap between pump head and holder was
closed. Overtighten the screws may damage the threads.
The housing screws of the internal pumps (external V4A)
were made from titan and, thus, are 100 % salt water proof.
Use your ngers to grab behind the needle wheel and soft-
ly pull the wheel from its guidance. Clean the wheel by the
help of a sharp tip (for example with a Nail le).
Please decalcify the wheel unit in an applicable decalcify-
ing bath.
DO NEVER use hydrochloric acid even
when thoroughly diluted!!!
The pump may be seriously damaged.
Applicable are, formic acid, acetic acid and phosphoric
acid or even household decalciers for water conditioners
and coffee machines. Basically the wheel bearing of the
motor should be also decalcied. Thick, greasy residues
should be removed under running water by the help of a
semi hard brush.
Attention:
Please consider the safety regulations imprinted when
using decalciers. Please wear protective clothing and
safety glasses.

We recommend to check the Red Dragon®pump already
after three months, to determine the possible maintenance
intervals that, can be depending on precipitation between
2-12 months.
If the impeller group extremely calcied,
solve the plate between engine and rotor. Cover enter
with a small slot screwdriver, !carefully!
2.2. Deliming and cleaning the impeller
If the bearing ts on the shaft, like shown on the picture on
the left, when pulled out, then manually remove it from the
shaft. And the bearing after removal from the shaft.
(Shown on the picture on the right)
Important notice:
The backside bearing of the wheel unit
should have your special attention, because most
failures result from there.
Under no circumstances put the bearing loosely onto the
shaft and then insert the wheel unit into the motor block.
The bearing wont t in its slide, and thus, the pump will
hum extremely after putting into operation. The bearing
must securely installed into its slide before assembling the
wheel unit. After the bearing was installed into its slide,
the O-ring seal must be seated by the help of a mid-size
screw driver.
After thoroughly rinsing of all decalcied parts with water,
we now begin to reassemble the device.
At rst, check if the bearing sleeve of the wheel unit on the
back was seated properly. Now take the wheel unit and
position in a way that the rectangular slide shows upward.
This rectangular slide will t into the motor only, when
showing upwards. Wheel unit with slide and the counter-
part on the motor shown on the picture on the left.

3. Disassembling and cleaning
the riser tube of the skimmer
All internal Bubble King®skimmers can be totally disas-
sembled. Thanks to new production processes with a pre-
cision range of 100/mm, all CNC-machined parts have a
so-called zero t. This means that most of the parts are not
bonded to each other, but feature precise ts.
All screws are made from pure titanium, grade 2, and are
absolutely seawater resistant and rustfree.
Please detach the skimmer in the lter tank as far as pos-
sible. Remove the pump, pull out the telescope tube and
unscrew the skimmer head. Please prevent the head from
falling off sideways. Clean the parts as far as possible by
a soft material and decalcify if necessary.
Please do not use sharp, abrasive or acid cleansers,
because the plexiglass is sensitive
to scratches.
Do not use hot-water over 50°C !
3.1. Disassembling the Plexiglas®riser tube
from the base plate (only internal skimmers)
From the date of manufacturing as 2007, 05th, Bubble
King®skimmers are not glued to the base plate anymore,
but rmly xed by screws. This allows lifting the riser tube
from the base plate to make the innards accessible to thor-
ough cleaning. Please proceed as follows:
First untighten the screws with an adequate screw driver.
Lift the tube from the base plate.
Caution: The PVC-linkers are very
sensitive. DO NOT DROP!
After cleaning, reseat the tube into the bearing
(g. left below) and tighten softly.
Attention: Do not overtighten the screws in the base plate.
Untighten the screw from the jet pan with an Philips-tip
screw driver.
The jet pan opened (g. left below). The bubble distribu-
tion plate cannot be removed from the riser tube. Access
for cleaning is available through the upper opening (g.
right below).
Hint for an optimal cleaning: The skimmer tube should be
rinsed under owing water with some chlorine. Chlorine
doesn’t damage the skimmer parts.

4. Maintenance
of the skimmer head PVC thread
All Bubble King®skimmers
have a CNC-milled PVC-
thread, providing 100%
tightness of the head in-
stalled to the skimmer tube.
After every thorough cleans-
ing the thread should be lu-
bricated by some silicone
grease or oil, which makes
the head much easier to
spin. The surface of the
seal should be also treated
by some oil, which allows
a smoother seating of the
head and adds more tightness. The seal itself was made
from silicone and, thus, is permanently salt water proof.
5. Maintenance of the resonator / silencer
Bubble King®skimmers are extremely low-noise. The
noise of the air jet is perfectly dimmed by a valuable reso-
nator. The so called Helmholtz-Resonator reduces noise
by frequency phase shifting. The Royal Exclusiv®resona-
tors are mostly maintenance-free, because the air is not
forced through lters like in other devices, but smoothly
pass through the resonator.
Dusty air or accidentally dipping the resonator into salt
water may require an internal cleaning to prevent plugging
from accumulated salt crystals.
Please check the resonator for obstructions by manual-
ly blowing through it. If you experience some resistance
please proceed as follows:
Open the resonator by the use of a matching M5 tool.
Thoroughly clean the resonator and reassemble. The left
gure below shows the opened resonator.
Thoroughly clean the resonator and reassemble. The cel-
lular material is only helpful for noise reduction but must
not be replaced if not desired.
Please do not overtighten the screws.
6. General
Important: correctly seated adjustable nozzle (only internal)
The noozle ts tightly into a notch and is removable. After
cleaning the nozzle please check that it was completely
pressed into the notch, like shown in the left gure. The
nozzle must be rmly seated. If the nozzle was not rmly
seated the consequences are equal to a wide open noz-
zle screw causing huge water ow and turbulences in the
skimmer.
6.1. Ozon plug
Please remove the hose from below the resonator and in-
stall a 12mm T-set auf. Install another hose on the lower
end of the T-set. The 12mm T-opening must be reduced
to 6mm and tted with a nozzle. Plug the ozoniser to the
small nozzle.
Usually the depression of the Bubble King®pump is suf-
cient to provide enough suction to the ozone. If the hose
is too long you may use a small air pump to feed the air-
ozone mix into the skimmer.
Under no circumstances try to connect the 10mm
silicone hose from the Bubble King®pump directly to the
ozoniser. It is denitely not functional!
The high resistance of ozonisers make it impossible to
be directly driven through the pump. The skimmer per-
formance would be instantly reduced by 90 %.The pump
would be overloaded and the safety circuit will emergency
shut off the pump to prevent damage to the pump.
