6. Problems
Adjustments:
Due to the construction, air and water mixing is done automatically - but you can
increase the amount of air and water by removing the grey reduction piece from the suction side of
the pump. To do so, the flow rate and the sucked in air will increase. If the foam is too wet, use the
elongation and lower the water level by turning or taking off the reduction piece.
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 approx. one day, the aquarium load will be normal and the
skimmer will produce correct foam.
Dry foam / no air bubbles:
Not enough foam or too dry foam could be an indication that the
mesh wheel is dirty or the venturi is obstructed. A thorough cleaning is recommended. Remove the
hose connection from the pressure side of the pump. Move the flap inside the pump from one side
to the other until it can be moved easily.
Turn the pump around and shake it. Now, you have to hear the flap. If not, clean it again. If it’s not
a problem of cleaning, increase the water level inside the skimmer with the two flow control taps.
Take the elongation between foam cup and skimmer and/or the grey reduction piece from the
suction side of the pump away.
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 done with the air
injection nozzle and the flap on the pressure side.
