Set up: beside or inside the filter tank of a sump or under tank filter system (Fig. 4):
The Turboflotor Blue 3000 can also be used in a sump or under tank filter system. It can be placed
either in- or outside the filter.
See the above hang-on procedures for installing the skimmer on the outside of the filter tank. It is
attached to the frame of the filter tank. If the filter tank is not high enough, the skimmer is placed
beside the tank. For the return flow, outflow boxes may be used. If the water level in the filter tank
is very low or there is a shortage of space in the tank, the 90°-elbow fitting (Fig. 1, No. 12) may be
connected to the outlet and the water will then be directed down to the water surface in the tank.
This avoids splashing and reduces noise. The venturi pump is fixed inside the filter tank in such a
way that it will not run dry and the length of the pressure tube has to be kept as short as possible
(Fig. 4). The pump should be placed close to the water surface. To prevent the pump running dry,
we recommend to use an automatic level controller (e. g. aquaniveau or Niveaumat) to ensure
replacement of evaporated water and to keep the water level in the filter constant.
5. Starting/Performance
The system can be started when the Turboflotor is correctly installed. After switching the pump on,
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 device on
the aquarium or the filter system.
The mesh wheel breaks the air into small bubbles. This method eliminates the greater proportion of
the noise. After the initial start, some hours may pass before the first foam is pushed into the
collection cup. This is due to a reaction between the surface of the 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.
6. Problems
Adjustment
The skimmer is adjusted using the flow control (Fig. 1, No. 5) so it works to the optimum. This
adjusts the water level in the reaction chamber. If the foam is too wet, even when the flow control is
fully open, the neck extension (9) can be mounted to adjust the foam production.
Air bubbles
Reduce the length of the hose between pump and skimmer. The pump should be placed close to the
surface otherwise more air and less water will be sucked in because of the increasing water
pressure. Result: Many air bubbles are leaving the skimmer, wet foam will fill the foam cup in a very
short time.
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 the organic substances effectively, however, it may be 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.
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.
Wet foam
With freshly prepared sea water, 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 approximately one day, the aquarium load will be normal and the
skimmer will produce the correct foam.
