6. Problems
Adjustment
The skimmer is adjusted using the flow control (Fig. 1, No. 5) as well as the electronic control DC Runner
Controller so it works to the optimum. The water level in the skimmer is adapted to foam production. If the
foam is too wet even when the flow control tap is fully open, the neck extension (Fig. 1, No. 9, not included)
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, especially, it the food is not thawn and washed prior to
feeding it to the fish. The air bubbles will stop after a short period by themselves. Greases will stop the
skimming completely.
Wet foam
With freshly prepared salt 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. If it is not
getting any better, first of all lower the water level in the skimmer by opening the control flow. Furthermore,
reduce the length of the hose (see air bubbles), use neck extension.
In new set-up aquaria, there is usually no reasonable skimming. The skimmer produces large
quantities of wet foam. This is normal and can be adjusted with the controller until the foam cup is
no longer full.
Dry foam
Not enough or too dry foam could be an indication that the needle wheel or air injection nozzle is dirty. A
thorough cleaning is recommended. Remove the pressure fitting from the pump. If it's not a problem of
cleaning, increase water level inside the skimmer by the water level controller. Remove neck extension.
7. Maintenance
The collection cup should be cleaned regularly (daily or weekly, depending on organic load). The reaction pipe
of the skimmer needs to be cleaned only occasionally. The venturi pump should also be removed and cleaned
regularly so there is no negative impact on the air output. The pump has to be removed and the complete
pump housing and needle wheel flushed with clean water. The same procedure should be undertaken with the
air injection nozzle.
