Internal filter sera F 400 - is it possible to redirect the water current?
Do you have the instructions for use for the sera F 400 filter?
the instructions can be downloaded from our web site, and of course we also e-mail them on request!
I would like to know whether the upper part (the "block") needs to be entirely submerged.
Yes, the filter must indeed be completely submerged.
I would like to agitate the water surface somewhat stronger and therefore want to place the outlet tube in a higher location.
In this case you can redirect the water current, e.g. with a hose pushed onto the outlet nozzle or by using a pipe system made of PVC pipe and angled connectors.
The sera fil 60 und 120 filters provide an alternative that already includes this option. These filters also make use of a sponge cartridge, which is, however, located inside a casing.
