Aquarium frames have to be cut so an open space of 285 x 40 mm is created.
Starting the system:
When
the
filter
is
assembled
completely, the pump can be started.
If the foam is too wet, reduce air by
using the valve. The water level
inside the filter chamber should be 2
- 3 cm lower than the shaft of the
biorotor. From time to time, the foam
of the biorotor has to be cleaned with
warm saltwater. Align the filter with
the aquarium by using the screw on
the bottom of the filter housing. To
do so, a screw driver is needed.
Adjustments:
Due to construction,
air and water mixing is done
automatically and no adjustment is
required. The regulation valve (17)
allows to adjust air and foam
quantity.
Air bubbles:
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.
