Bio media in overflow ???

  • We are currently upgrading MFK. thanks! -neo
nothing in the over flow box. if anything at all, just sponge or floss but i'd let it all flow down to the sump.
 
I don't have biomedia in my overflow either. I just have porous sponges as prefilters to catch some of the debris over the piping. Not enough to consider as biomedia though.
