3 Installation
There are 4 ways to position the filter on your aquarium.
1 Hanging on the left of the aquarium 
2 Hanging in the middle of the aquarium 
3 Hanging on the right of the aquarium 
4 Standing next to the aquarium 
When you unpack the filter you will see that it has been prepared for use in
position 1. To use it in a different position, adjust the filter as shown in Fig. 5 – 7.
If you want to run a standing filter, do not place the filter lower than 60 cm
below the aquarium since this exceeds the maximum head.
For shrimp aquariums, add intake protection (filter sponge) to the suction pipe
to avoid sucking up young shrimp. 
4 Startup
• Before switching on your filter, check all tube connections to ensure they
are seated correctly, and (re)tighten the screwcaps where necessary.
This ensures that the tubes are installed correctly .
- Turn the screwcap (a) clockwise as far as it will go.
- Attach the elastic corner piece (b) or insert the tube as far as it will go.
- Turn the screwcap by hand anti-clockwise as far as it will go. Be sure to
hold on to the corner piece so that it is not pushed down by the tube
connectors.
• Rotate the stoppers a quarter turn to the left and remove them. 
• Refill the filter completely with water. Replace and tighten the stoppers
again. 
• Plug the power cord into the mains outlet to start the filter.
5 Filter and lily pipe hanging position
There are 2 possible positions for hanging the filter in an aquarium.
1 Lower position = lily pipe fully submerged 
In this position the lily pipe generates gentle, natural currents below the
water's surface. Minimal surface movement prevents unnecessary CO
2 Upper position = lily pipe approximately 2/3 submerged 
The "rippling" water return in this position delivers a rapid supply of
oxygen. This is an important emergency measure if there is a lack of
oxygen, as indicated by fish breathing faster.
Vortices are formed that drag surface residues (film) under water, which are
then filtered out.
Tip: Hang the filter in the lower position during the day, switching to the
upper position at night. This saves you valuable CO
when plants do not consume any CO
your fish, the water is enriched with oxygen.
Lily pipes can be adjusted up or down by around 10 mm in line with water
levels, and they can also be rotated. Lily pipes should be positioned so as to
generate even, gentle water currents throughout the entire aquarium – ideal
for verdant plant growth.
6 Cleaning and care
6.1 Cleaning and replacing filter material
• Clean filter media regularly to maintain optimum water flow.
• Remove the plug from the power outlet.
• You can remove the filter from the aquarium entirely.
• Open the 4 sealing clamps and remove the filter head. 
• Remove the filter element. Separate the cover and filter baskets by
pressing on the retaining clips 
The pre-filter materials in the lower filter basket – filter sponge and fine
filter pad – should be washed with aquarium water during each cleaning
process, and should be replaced as necessary.
You only need to clean the bio filter tubes responsible for biological
cleaning in the upper filter basket if they are obviously silted up. We
recommend washing the tubes in aquarium water so as not to affect the
performance of the filter bacteria. Because the pores gradually close up
over time and reduce performance, we recommend replacing half of
the bio filter tubes around every 6 months with fresh filter material
(item no. 5603).
• Reassemble the filter baskets in the correct order (sponge at the bottom,
tubes at the top) and replace the cap.
CAUTION: Make sure to replace the filter head so that the pump
suction tubes fit into the cap opening!
Close the 4 sealing clips and start the filter as described in point 4.
