The sera marin Protein Skimmer PS 130 is a small and
powerful skimmer suitable for aquariums up to approx.
150 liters (40 US gal.). It is attached to the aquarium glass
edge or the lter chamber by means of the gray holder
bracket. The unit is included with the sera marin Biotop
Cube 130 kit. However, it is also suitable for smaller
tanks due to its size. It is therefore also optimally suit-
able for aquarists who wish to start a marine aquarium
after having kept freshwater aquariums.

3.3 Air hose with adjustment valve
3.4 Vertically adjustable holder bracket
Skimmer tasks
A skimmer is the heart of marine aquarium ltration. It
removes protein that is permanently released into the
water by micro organisms, invertebrates and sh. The
skimmer removes particles such as oating matter and
aerates the aquarium. Protein not removed from the wa-
ter will lead to an increasing amount of harmful substanc-
es such as ammonia, nitrite and nitrate (bacterial break-
down chain beginning with protein). Keeping marine
organisms in closed systems would be considerably
more difcult or, depending on the requirements of the
species in question, even impossible.
Function principle (4)
The dispergator pump draws in air through the hose (4.1)
and blends it with water drawn in through the slits of the
bottom part of the unit (4.2). The water/air mixture is di-
rected into the inner reaction chamber of the skimmer
(4.3) and rises to the water surface inside the unit. The
bubbles form, pass the otate cup sieve (4.4) and col-
lect in the otate cup (4.5), whereas the water enters the
outer chamber of the unit and leaves the skimmer
through the outlet tube (4.6) with adjustment valve at-
tached on the side.

The sera marin Protein Skimmer PS 130 is installed in
the right lter chamber, where the water enters ltration
in case of the sera marin Biotop Cube 130.
The unit can of course also be operated in other similar-
ly sized aquariums. The unit is attached to the upper
edge of the back or side aquarium pane by means of the
gray holder bracket. The snap-in points allow for precise
vertical adjustment of the skimmer. It is recommended
to immerse the skimmer in the aquarium up to the up-
per gray ring. The air hose of the unit must protrude out
of the water, and the stick-on valve that allows adjust-
ing the air intake must be entirely open. The adjustable
outlet of the unit is located below the water surface.
The skimmer is now ready for operation and can be started.
Operation
After switching on the pump, air is automatically drawn
into the skimmer and scattered into ne bubbles by the
rotor of the pump. The water level inside the skimmer
rises slightly above the water level of the lter or the
aquarium, respectively. The pump will now blend water
and air. Starting a skimmer for the rst time will often
lead to relatively strong foam formation: Extremely moist
foam will end up in the otate cup (5.2) which quickly
runs full of water this way. In that case a temporarily re-
duced air intake at the air regulator (5.12) or a very low
water level inside the skimmer will help. For achieving
this purpose, re-adjusting the holder bracket (5.9) allows
placing the unit in a position protruding higher above the
water surface. Additionally, the water level inside the
skimmer can be adjusted by the outlet valve. Each aquar-
ium has its own biology and its own protein level.
One day after starting the unit you should adjust it more pre-
cisely for the rst time, in case too much liquid is skimmed
as well as in case no foam has formed: If no foam has ap-
peared so far, the skimmer should be immersed deeper.
