In this manner, flow of water from the Pump (G) and the flow of air from the Air Silencer
(F) are always maximized. Initially the foam may be fairly wet in nature. To make the foam
more concentrated in waste, lower the level. If very little foam is climbing over the edge
of the cup after a few days then raise the level. It is normal that in the first few days of
operation, the skimmer may fill with a clear liquid. In time, the collected liquid (skimate)
will become darker in color and more concentrated with waste from the aquarium. Fine
adjustments can be made by turning the Air Intake Screw (F.1) on the Air Silencer (F)
however this would should only be done when there is simply too much foam created and
the foam cannot be controlled by lowering the water level by adjusting the Drain Tube (E)
and Drain Spillway (H).from the aquarium.
NOTE: While most marine or saltwater can be skimmed easily, a specific gravity of 1.026 or a
salinity of 35 ppt is recommended for best results.
When used in completely new aquariums, the foam can be suppressed for several days. This
is temporary and is due to various rubber and plastic parts used to setup the aquarium having
compounds that inhibit foam.
In some special cases, the air intake can be regulated, but it is an operation to be carried out
after having acquired some experience with the skimmer. An excessive closure of the air supply
could damage the needle impeller of the pump.
Maintenance
1.
Before proceeding with maintenance, disconnect power to the Pump (F).
2.
Check the skimmer daily for the level of collected liquid (skimate). If the skimate continues
to be clear after a few days of operation, the level of foam can be lowered slightly to
concentrate the skimate more. If the foam does not continue to produce a skimate, then
the level of foam can be raised slightly. It is important to make adjustments in very small
increments and then allow time for the adjustment to take effect. The fine-tuning of the
skimmer level will come with experience.
3.
When the level of skimate in the Collection Cup (D) reaches 3-4 cm (1-2”), it is recommended
that the Collection Cup (D) be removed and cleaned. A cleaner inner column of the
Collection Cup (D) results in better skimate production. As an option the Collection Cup (D)
has a drain where a small hose can be connected to drain into a larger reservoir such as a
small bucket or jug for longer periods between cleaning.
4.
It is recommended to check the Air Silencer (F) and the Tubing (N) weekly to make sure they
are clear of any salt, dust or dirt build up. An increase in noise or vibration can indicate an
obstruction of air flow.
