Bio Balls: Yeah or Neah

Hehe, well they have definately been neglected. I guess I'll slowly start removing them as I'm really gonna need some room for an in sump skimmer.
I really need to redesign this sump, kake the 1st chamber just wide enough to accomadate a skimmer, then try and make the rest into a reurg/retrun chamber (sep by eggcrate?). A 20g tank sure gets used up quick
