Uniquarium for qt. Bioballs leave or remove?

I purchased a used uniquarium for quarantine. It comes with blue bio balls in a rear chamber. Should I leave them there or remove them? Thank you in advance.

You can leave them in place, they are inert. However, the surface area for bacteria on these is really a lot less than people think. The little sponges over to the right would contain a lot more surface area.

Thank you for your reply. I have already taken them out as I did not think they did very much. I just wanted to check if they would be beneficial as I would’ve put them back in.
I will just put in filter floss and cut up filter socks that have been in the sump of my 180 gallon display.
