2. Principle of Operation
The aquarium water is pumped to the skimmer using a separate pump (not included in delivery)
which should have a capacity of approx. 2,000 - 4,000 litres/hour. The relative positions of the
inlet and outlet ports ensures the maximum contact time of air bubbles in the counter-current. If
the SHORTY COMPACT is mounted in the cabinet, it can be supplied with water directly from the
overflow of the aquarium. In this case, a bypass should be installed so the volume of water can be
adjusted.
The venturi pump draws water from the skimmer and mixes it with air. Within the pump housing,
the bubbles are cut into very fine pieces by the AB Aqua Medic needle wheel. The air/water mixture
is pumped back into the skimmer.
The treated water flows out of the bottom of the skimmer and is pumped through the two
transparent pipes positioned outside the skimmer back into the aquarium or filter sump.
3. Installation
•
Check that the sealing rings for the unions are in place.
•
Slot the holding plate for the venturi pump to one side of the skimmer. Push pump on to the
holding plate and connect the pump to its union.
The PVC air tube should be fed so that the end is higher than the water level in the skimmer.
This air tube must not hang down.
It should only be out just 5 cm at the top.
Connect the bottom end of the tube to the air intake of the pump.
•
The water inlet is located at the same side as the outlet pipes. Attach the union and hose tail
(20 mm).
•
We recommend a pump with a capacity of 2,000 to 4,000 litres/hour for the water supply or
direct connection to the aquarium overflow.
•
Fit the rubber sealing ring for the bayonet socket of the reaction pipe.
Push foam cup into its seating and turn it to lock.
The drain from the skimmer has to run freely into the aquarium. A PVC pipe (40 mm dia) can be
glued into the drain ports. It is possible to let both drains flow into one pipe but the diameter of the
pipe must not be reduced. If the drains are left separate, a reduction in pipe size to 32 mm is
possible.
The skimmer can now be filled by pumping directly from the aquarium. Ensure that the water level
of the aquarium is not lowered too much. As soon as the water level in the skimmer reaches the
height of the venturi pumps, these pumps should be started.
Top up with sea water as necessary.
After first use or after cleaning the skimmer, it takes some time for the initial foam to build up in
the reaction pipe of the collection cup. This is because the cleaned acrylic initially reacts with
water until a build up of fatty acids naturally takes place.
After approx. 24 hours, the foam should be pushed slowly and evenly into the collection cup. The
quantity of liquid and organic substances depends on the pollution of the aquarium.
