3.4. Maintenance / Cleaning the pump
Depending on contamination, the pump has to be cleaned occasionally, at least in two-month intervals, if
necessary more frequently.
First of all, remove the retaining plate. Then, take off the pump lock (Fig. 2, No. 9). Now, the complete
impeller (Fig. 2, No. 5) can be taken out. Caution: This part is tight fit and has to be removed carefully so
as not to break the ceramic shaft. It can be cleaned under running water and then be re-assembled.

Starting the skimmer
The air tube has always to be installed upward over the water level in the skimmer. This air tube must
•
not hang down. Therefore, it should always be connected to the silencer (Fig. 1, No. 5). Connect the
bottom end of the tube to the air intake of the pump. The air inflow (Fig. 1, No. 8) should principally be
fully open. An adjustment of the inflow would change the water flow at the same time and therefore,
should only be done in exceptional cases.
The foam cup is simply inserted from the top.
•
The ideal water level in the filter sump is 13 ± 1 cm for the aCone 1.0 EVO. With higher or lower water
•
levels, airflow rate and skimming power will decrease. The filter sump should either contain an overflow
edge that keeps the water level in the ideal range or it should be equipped with an automatic refill unit,
such as Aqua Medic Refill System. The drain from the skimmer has to run freely into the aquarium or
filter sump.
The skimmer will be filled by starting the venturi pump. To do so, first of all open the lower drain valve
•
(Fig. 1, No. 7) completely. With high water load, the valve can also be unscrewed completely. If the
water level remains constant, it has to be closed only so far until the skimmer is filled to half or two-
thirds. Afterwards, wait for some time and make the fine adjustment with the upper adjusting screw,
best one to two hours later. A water level too high leads to very fast overflowing of the foam cup. Here,
special caution is required, if one connects the outflow nozzle of the foam cup via a hose with a container
standing beside the filter sump. There is the danger that the container overflows if the skimmer cooks
over. Thus, this would also lead to strong loss of water in the filter sump whereby other devices could
run dry and therefore, could be damaged.
Ensure, when filling the skimmer that the water level of the aquarium resp. filter sump is not lowered too
•
much. Possibly, keep freshly prepared saltwater ready for refilling.
After first use or after cleaning the skimmer, it takes some time for the initial foam to build up in the
•
reaction pipe of the collection cup. This is because the cleaned acrylic initially reacts with the water until
a build up of fatty acids naturally takes place.
After approx. 24 hours, the foam should be pushed slowly and evenly into the collection cup. The
•
quantity of liquid and organic substances depends on the pollution of the aquarium.

Maintenance
Foam cup: Depending on the organic load, the cup should be cleaned daily to weekly.
•
Skimmer pipe: This only needs occasional cleaning. We recommend intervals from 6 to 12 months.
