Hi guys, today I just decided to replace my cheapo Overhangfilter with the eheim 2040 ohf and bought a pack of biohome.

But due to the space constraint I am only able to put the biohome first then follow by the cartridge sponge provided.

Is there anyone with this filter able to show me how you diy ur filter so that biohome is at the last stage? Or is It ok just to let biohome be the first media?

Thanks for reading!
