Thanks Loubard!Filter and tank looking good! What are you using for bio material?
The top crate is empty, its to create a nice shower for the next crates.
In the second I have sponge mats (sorry don't know the correct english name)

In the third I have large bioballs, can barely see them in this pic

And in the two last crates I use the small bioballs (Kaldnes K1)

More or less the same materials I use in a sumpfilter for a couple of my smaller tanks.

I'm planning to take better pictures of the tank with my brothers camera, these pics are taken with my mobile phone...
