1. Installation (putting into operation)
Take the Mini Bubble King (MBK) out of the package and
check the skimmer for shipping damages. Your local dealer
must be notied about any damages within 24 hours. The
Mini Bubble King (MBK) is pre-installed and ready for opera-
tion and may be put into the lter sump for instant operation.
In order to get familiar with the device, do not install the
skimmer head yet.
The lower water level of the Mini Bubble King should not
be below 13 cm and should not exceed 30 cm.
The water level should ideally be between 20 and 22 cm.
Plug the power cable into the corresponding socket.
Please note that sub water level pumps require a ground
fault circuit interrupter (FI safety switch).
Furthermore we recommend a frame connector with volt-
age surge protection which, in the case of a short circuit
in the mains, protects the Red Dragon® (RD) pump from
electric shocks which would burn the internal fuse.
The used Red Dragon®6pump works with 12V supplied
with a Multi-Range-Power-Supply from MeanWell.
Shortly after the pump is put into operation, a foam cush-
ion should appear, as demonstrated on the gure below.
(skimmer after starting the pump 1 - 2 - 3 - 4)
Run the skimmer in this way for several hours without the
skimmer head.
It takes a while
for new skimmers to be able
to produce solid foam.
New skimmers may contain several substances such as
grease and glue residue which prevent foam from forming.
Depending on the contamination of your aquarium water
it may take from 2 minutes up to 1 week for solid foam to
form. It is not possible to make an accurate prediction as to
how long it will take for the skimmer to be properly run in.
Once the foam is solid enough, place the skimmer head
on the skimmer post. Before installing the skimmer head
make sure that the internal red O-ring is correctly placed
with no ripples or similar irregularities. These may cause
slight leakage.
If the foam is sufciently solid, the water level can be ad-
justed by turning the wedge shaped tube clockwise or
counter-clockwise.
The small screw on the side of the wedge-shaped tube
fastens the tube to its holder. The tool should only be light-
ly screwed and without the use of tools.

Max. water level
Current
water level
The gure above shows how the water outow can be
regulated by turning the wedge.
Please note the maximum water level. The water to air
stripline is the level after which wet foam becomes dry
foam. The water level should not exceed the indicated wa-
ter strip line. This line ensures dry foaming.
Our recommendation is a guideline. The line may be ex-
ceeded if necessary. It at the discretion of the user to de-
cide whether he prefers wet or dry foam.
Once the skimmer has formed enough dry foam, it is re-
commended to grease the upper end of the riser tube as
well as the inner foam ring. This will prevent the foam cup
from being lled with solid dry foam because the bubbles
will burst as soon as they come into contact with the
grease. This way, only the adsorbate will enter the cup.
The dry foam might leave the cup through the ventilation
holes and fall back into the lter sump.
On the gure above, the water level stripline is approx.
4 cm below the maximum level. This water level stripline
can be lowered or increased by turning the tube.
The water level stripline is different for every aquarium, de-
pending on the quality and surface tension of the salt water.
Keep the skimmer running until the foamy liquid has lled
the absorbate pot (skimmer head).
All Bubble King®skimmers have a so called “absorbate
drain”. The 10 mm hole at the bottom of the pot (skimmer
head) is sealed by a silicone plug. This is the hand-over
location. The customer may install an additional attach-
ment (e.g. a small ball tap) to drain the absorbate, which
facilitates cleaning.
Note:
Please do not wait too long until cleaning
an over-lled pot.
2. Maintenance + disassembling of the skimmer
We recommend checking the Mini Bubble King at regular
intervals to check for impurities on the needle wheel. This
does not require removing the skimmer from the lter.
Disconnect the skimmer from the mains by unplugging the
nozzle. Then turn the skimmer in your direction to see if
any foreign objects such as snails, mussels, activated car-
bon pellets, lter cotton or food debris have entered the
rst row of needles. In case of an accumulation of debris
in the pump, the pump must be disassembled.
Pull the suction nozzle from its tting slot/ute. (Fig.: re-
move the suction inlet to the control of the needle wheel).
All Red Dragon Bubble King®pumps have a built-in auto-
matic shut-off. The internal circuit is permanently measu-
ring the power consumption of the pumps. In the case of
serious calcifying, and thus, stiff bearings, the internal cir-
cuit will identify the rising power consumption as a failure
and will switch off the pump for safety reasons.
This protects the Bubble King® pump from internal res
and other damages, such as short circuit resulting from
overcharge. The pump can be brought back into operation

by switching the plug on and off.
We do not advise repeatedly switching on and off to force
the internal pump back into operation. If a Red Dragon®
pump switched itself off, there is a defect which needs to
be resolved. Often, a cleaning is all that is required.
Permanently tricking the circuit may result in severe con-
troller damage, which is not covered by warranty.
Once the individual parts of the skimmer have been re-
moved from the lter tank, remove the jet tube (nozzle)
from its holder and put the skimmer onto a at, soft sur-
face or a towel and start to disassemble the Mini Bubble
King as shown below. A standard mid-size screw driver is
required for a complete disassembly.
Take the skimmer-pot and the
resonator off. Then remove the air
hose from the nozzle and pull
those with slight rotation and
press movements due to the
wedge tube. Now you can
remove the wedge pipe.
First untighten the plastic screw of the injection pan, which
you can then extract from the body. If you turn the screw
connection, remove also the base of the injection pan from
the body. As soon as the titanium screws at the bottom are
solved, can the pump be pulled with the lower bottom plate
carefully from the body of the skimmer. Refer to the follow-
ing images in a logical sequence.

3. Maintenance and cleaning of the RD6
Please undo the 2 titanium screws on the base plate. To
do this, please use a sufciently large screwdriver. After
undoing the screws, pull release the complete motor-block
out of the column (gure below: removal of the pump).
Open the union nut and pull the housing cover to the front.
Pull out the wheel unit from the front. If the wheel unit is
extremely calcied, carefully insert a small screw driver
into the gap between the motor block and housing cover,
then lift slightly.
Caution: Never apply force to the wheel unit.
Disconnect the pump from the power supply prior to each
maintenance work. Red Dragon® supply- and ow pumps
are essentially to be classied as low-maintenance. Usu-
ally the necessary maintenance work is limited to a check
of the impeller for obstruction. Remove obstacles from the
impeller with a slim and spiky tool. A decreasing supply
rate is often the result of dirt. Possible calcinations (espe-
cially in saltwater applications) has to be removed with a
very soft acid as for instance vinegar. Avoid applying pres-
sure to the sides of the impeller or the rotor. The pump can
be disassembled nearly completely for cleaning.
In freshwater- and saltwater applications calcication only
appears in very hard water and after a complete re-lling
of the pond. After this the largest amount of carbonate will
be omitted within 2-3 days.
If necessary the impeller unit can be removed, by cau-
tiously pulling on the rotor. When you pull on the rotor, be
very careful, as the impeller is held in its position by the
magnet. If you release the rotor while trying to pull it out,
the bearing can get a serious damage.
Do not underestimate the power of the magnet.
If you slightly lose the grip and the axis hits the rear
bearing, the risk to damage the bearing is very high.
A damage bearing causes high reparation costs.
Grab rotor and cautiously pull out completely.
Check parts for calcication.
After the maintenance you can assemble the pump in
reversed order. Please pay attention to rst only loosely
x the in crossed over order and then x them semi-solid
(hand tight).
The O-seals of the pump are made from silicone or EPDM/
Viton, depending on the application.
Please use only fresh and original O-seals with the correct
thickness and hardness as replacement. When O-seals
are aging, the hardness slightly changes. When you re-as-
semble the pump, the O-seals should always be replaced
by new ones. This will increase the lifespan of the pump.
Silicone and EPDM / Viton O-seals are resistant against
acids and bases.
Decalcify the pump completely. Please do not use hy-
drochloric acid, not even in extenuated form. This may
damage the pump beyond repair. After the decalcication
purge the pump with clear water. Re-assemble the pump.
Decalcify the wheel unit using
a suitable decalcifying bath.
NEVER use hydrochloric acid even if diluted!!!
The pump could get seriously damaged.

4. Assembly of the skimmer
After a complete cleaning, reassemble the skimmer ac-
cording to the following instructions:
Start by reassemble the pump rst. Carefully insert the ro-
tor in the engine block.
Tighten the four screws until the gap between
housing cover and motor block is closed.
DO NOT overtighten the screws.
Fix the pump on the lower bottom plate and place the
skimmer body. Caution: pay attention to the correct seat
of the cable of the pump. Insert the bottom plate screws
and tighten moderately. Also please do not work with too
much force.
At the base of the injection pan depicted on the right po-
sition, as shown above, respected the ute/groove. Now
replace the pan-like shaped base plate and tighten it softly.
The injection pan should be relatively centered in the mid-
dle of the tube. Please note: It is important to place the
side with no holes on the pressure nozzle of the pump,
rather than the side with holes.
Next, pull the silicone tube through the tube, with one end
attached to the nozzle and the other to the silencer. Finally,
check the silencer.
The upper cover is only loosely stuck on and should be
removed easily. If this is not the case, insert a screw driver
from the bottom side of the 10 mm air tube and gently hit
the cover. The cover should then be removed easily and
the silencer becomes accessible.
Replace the cover after cleaning. Please do not insert cot-
ton wool or activated carbon into the silencer. We explicitly
point out that the pump cannot be operated in dry run.
The pump may under no circumstances be operated on a
dry run, even for testing purposes. Doing so may result in
instant damage.
As a last step, reassemble the red suction tube with the
nozzle and ensure tight t, connect air hose. The skimmer
is now operational again.
5. Power outages and emergency power supply
After a blackout the pump will start automatically and the
controller will set up the last chosen speed.
The pump can be used on a commercial emergency power
supply or a commercial UPS, which is tted with a rectier
package.

Important:
When removing the skimmer from the lter basin,
it is essential to ensure
that no salt water enters the silencer!
This could lead to
salt crystal formation,
which would hamper the performance
of the silencer
and
produce unpleasant noises.
6. Resonator
The pictures below show the opening of the resonator.
The silencer inlay may now be rinsed with fresh water, but
must be completely dry before being reinstalled!

8. Possible sources of error
For optimal skimming results,
please note the following information:
1. No water is the same! As a result of the different com-
position, the skimmer may need a few days before it
starts to skim.
(Particularly with new products)
2. Pay attention to the water lling level between
from ~ 130 mm up to ~ 300 mm (ideally ~ 210 mm)
this is the height of the water in the lter basin!
3. The water level in the skimmer is controlled using a
tube. This sets the amount of foam to be produced.
(The level of water in the skimmer is set by turning
it left or right).
4. If the skimmer produces a water-air mixture in the
tube when it is turned on, this means that the skim-
mer is operating correctly. The skimming default must
lie elsewhere.
5. Do not let the pump run dry -
this would lead to permanent damage!
6. A sufcient pre-ltering of the water before it en-
ters the skimmer, is recommended! So, the pump will
be spared as before large parts, such as snail shells
or shells, which can lead to a blockage of the needle
wheel.
For the skimmer to produce optimal results, the Mini Bub-
ble King must be brought to the correct height. This will
depend on the water ll level.
