PLACE OF LOCATION
Filter operation and problem solving
Noise reduction/ external air
Especially the suction intake /inlet and the connected suction surface must be
checked for tightness and adjusted according to the water level of the aquarium.
In case this is not possible due to aquarium technical reasons, seal the whole
suction surface so that no external air can get into the filter.
De-aerating/ evacuating air
Take the return-flow hose that conducts the water from the filter to the tank and lead it into a clean
bucket that is placed below the filter. Lead the hose into the bucket and carry out the dearation pro-
cess (evacuate the air) by activating the manual pump. Please make sure that the possible maximal
flow is adjusted to the inlet-outlet connector. As soon as no air bubbles can be seen, seal the hose
with a finger und and install it again as intended on the return pipe at the top
edge of the aquarium.
