Commissioning/start-up
N O T E
Remove the protective film from the substrate tubes and insert the substrate tubes into the container.
(→ Cleaning/replacing the substrate tubes)
• The substrate tubes are sealed in protective film on delivery.
• Thoroughly clean the pond before starting up the filter system for the first time to ensure that the filter system
is not overloaded by excessively soiled water. OASE recommends using the PondoVac pond vacuum cleaner
for cleaning the pond.
– This cleaning measure is normally not necessary for newly installed ponds.
• It is necessary to operate the filter system for 24 hours a day during the pond season.
4.1
Biological filter starter
The foam filters take several weeks to reach their full biological cleaning effect. We recommend using the
OASE filter starter Biokick to ensure fast growth of bacterial populations. Micro-organisms colonise the filter
system, multiply and ensure an enhanced quality of the pond water by the decomposition of excess nutrients.
N O T E
When using filter starter, medicines or pond water treatments, leave the UVC clarifying unit switched
off for at least 36 hours so as not to impair their efficacy.

Order of starting up steps
How to proceed:
1. Close the slide valve of the dirt outlet.
2. Check that the filter system (pipes and hoses) is complete.
3. Remove the container cover.
4. Connect the transformer for the control device to the power supply.
5. Switch on the filter pump and UVC clarifier (if applicable).
– Ensure that the water is returned to the pond via the return pipe.
6. Check all pipes, hoses and their connections for leaks.
– Expansion seals may leak initially until they have fully expanded on contact with water.
7. Adjust the control device to the flow rate if necessary. (→ Aligning the control device)
8. Check the function of the ScreenMatic rotating screen unit. (→ Operation)
9. Fit the container cover.
N O T E
The final water level is not reached in the container until the bacteria are established and the filter be-
comes fully effective.
• New foam filters take 3 to 4 weeks to reach their full biological cleaning effect. The water level is
initially lower; the foam filters are not completely covered by the water. The filter may overflow while
the beneficial bacteria colonies are being established. Do not clean the foam filters for 3 to 4 weeks.
• The biological cleaning effect ceases at temperatures under 10 °C. The filter may overflow. Clean-
ing is not necessary.
N O T E
The substrate tubes should remain completely under water to ensure maximum effectiveness. De-
pending on the system configuration, the level of the water in the container may be too low for this.
• In this case, place the top substrate tube directly into the pond at a point where there is good water
circulation.
