Since 1986
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 figure 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 fixed
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 filter should be designed to provide
high water flow through to the skimmer.
All Bubble King
®
DeLuxe models have an integrated drain
on the skimmer head
(see right fig. 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-filled pot.
By problems caused by low water level:
The pump inlet must not cause a swirl like shown on the
fig. 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 deflection 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.

All
internal
Bubble King
®
skimmers are fit with an adjust
-
able water inlet nozzle. Using the nozzle mainly adjusts
the water flow rarely affecting the air performance.
Please note:
A skimmer performs best, when a perfectly well defined
amount of water and air enters the skimmer on the lowest
point of the device. The Bubble King
