Dry foam:
Not enough foam or too dry a foam could be an indication that the needle wheel is
dirty, or the venturi is obstructed. A thorough cleaning is recommended.
6. Parts of the venturi pump
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 be cleaned at the same time. The pump has to be removed and the complete pump housing
and the needle wheel flushed with clean water. The same procedure should be undertaken with the
air injection nozzle.
8. Problems
Problems may arise if the relationship between drawn air and water is not in correct.
The reasons could be:
-
The air injection nozzle is clogged or the pump housing with the needle wheel is dirty (remove
and clean).
-
In calcareous aquarium water, the nozzles often can get clogged.
-
If the nozzle cannot be removed mechanically, the whole nozzle should be put into vinegar or
citrus acid over night.
