XP3

  • We are currently upgrading MFK. thanks! -neo
I have the sponges in the bottom. Then in the middle, fill it with ceramic cylinders. And in the upper basket I have mostly filter floss, and will sometimes add activated carbon if it's needed.
 
I use an XP3 and have a extra basket with nothing in it. I have extra Bioballs, Would they help with anything if I fill the empty basket with them?
