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.
Note!
The final water level is not reached in the container until the bacteria are established and the filter becomes
fully effective.
• The water level is initially lower when new foam filters are fitted; the foam filters are not completely covered
by the water.

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.
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.

Aligning the control device

Do not align the control device until after the running-in period
• Lowering the pump into the pond may swirl up so much debris that starting up the filter system straight
away could cause the ScreenMatic screen to overflow.
• The filter system requires a running-in period of 2 to 3 hours. After this, the control device can be aligned if
necessary.
• Align the control device such that the sensor only switches when a well-formed line of debris has formed on
the screen.
– A well-formed line of debris can be optimally removed by the stripper and conveyed into the debris tray.
– The stripper brush under the ScreenMatic screen collects the fine debris, which falls into the debris tray.
How to proceed:
 L
1. Remove the screw from the control device and take out the control device.
2. Insert the control device into the determined position, insert the screw and hand tighten.
Aligning the control device depending on the degree of soiling of the pond
In order to prevent premature soiling of the foam filters, ensure that the dirty water does not flow beyond the
"Max. water jet" mark directly into the debris tray.
• Do not change the position of the control device unless the water flows as far as or beyond the "Max. water
jet" mark, even when the ScreenMatic screen has been cleaned (with the enclosed brush).
