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. Greases will stop the skimming
completely.
If the air nozzle or air hose is blocked with salt or lime deposits, less air and more waters is sucked in. In this
case, clean both completely.
Wet foam
First of all, lower the water level in the skimmer by turning the water level controller (Fig. 1, No. 4). With freshly
prepared salt 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.
In new set-up aquaria, there is usually no reasonable skimming. The skimmer produces large
quantities of wet foam.
Dry foam / not enough bubbles
Not enough or too dry foam could be an indication that the impeller or air injection nozzle is dirty. A thorough
cleaning is recommended. Remove the pressure nozzle from the pump. If it's not a problem of cleaning, increase
water level inside the skimmer by the water level controller.
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 impeller flushed with clean water. The same procedure should be undertaken with the air injection
nozzle.
