4.5. Starting/Operation
The system can be started when the Turboflotor is correctly installed. After switching on the pump, air is
automatically drawn into the skimmer. To minimize the noise level, connect the air inlet tube with the
blue connecting piece of the silencer supplied. Fix the silencer with the holding unit (15) on the back side
of the filter partition wall. Please wipe the wall with a dry cloth at the requested place, take the foil off
the holding unit and press the unit thightly.
The mesh wheel breaks air into small bubbles. This method eliminates the greater proportion of noise.
After the initial start, some hours may pass before first foam is pushed into the collection cup. This is due
to a reaction between the surface of acrylic glass and aquarium water. Equilibrium of electrical charges
takes place. After a maximum of 24 hours, the foam should be pushed evenly into the collection cup. The
quantity of liquid and organic substances is dependent on the pollution of the aquarium.
4.6. Problems
Adjustment
The skimmer is adjusted using the water level controller so that it works to its optimum. The water level
in the skimmer has to be adapted to foam production. If the foam is too wet, the water level controller
(4) has to be further opened and thus the water level lowered. If the foam is too dry, the process has to
be done vice versa. The water level in the filter is regulated by the slide control in front of the
last filter chamber so that the water level is underneath the skimmer's discharge.
Air bubbles in the outflow
If the skimmer is added to an existing aquarium, there may be a high concentration of organic
substances already dissolved in the water. This results in very tiny bubbles in the skimmer. These tiny
bubbles remove organic substances effectively, however, it may happen that some of these bubbles are
drawn back into the aquarium. After a few days, the concentration of organic substances will have
decreased to such low levels that this effect will have gone and the water flow is free of air bubbles.
Very rarely, there's a reasonable adjustment in new established aquaria. Either the skimmer „cooks over"
or „bubbles "without foaming power. This is normal and will be settled by itself as soon as living animals
will be in the tank.
Some types of frozen food may have the same effects. It is best to thaw and wash the food prior to
feeding it to the fish. The air bubbles will stop after a short period by themselves.
If the air nozzle or air hose are blocked with salt or lime deposits, less air and more waters is sucked in.
In this case, clean both completely.
Wet foam
With freshly prepared sea water or after using water conditioners or at extremely high loading, excessive
wet foam may be produced. This wet foam is forced into the cup, requiring more frequent emptying than
normal. After approx. one day, the aquarium load should be normal and the skimmer will produce correct
foam. Lower water level in the skimmer by turning the water level controller (4). Maybe clean the air
injection nozzle, hose conncection and hose of deposits.
Dry foam / not enough bubbles
Not enough or too dry foam could be an indication that the mesh wheel or air injection nozzle are dirty. A
thorough cleaning is recommended. Remove pressure nozzle from the pump. If it's not a problem of
cleaning, increase water level inside the skimmer by the water level controller (4).
4.7. Maintenance
The collection cup should be cleaned regularly (daily or weekly, depending on the organic load). The
reaction pipe of the skimmer needs to be cleaned only once or twice a year. The venturi pump should also
be cleaned from time to time. The pump has to be removed and the complete pump housing and mesh
wheel flushed with clean water. The same procedure should be undertaken with the air injection nozzle.
