I would take it out unless you are doing fish only. It is a nitrate factory.

nothing just take out the bio balls. If you can convert it into a refugium that will be great for your reef.

If you have enough live rock, then you don't want to use the bioballs.
I'm assuming this is a already setup system that you are adding a sump to?
If you are it is a good time to arange the sump for all you needs. Consider adding partitions and baffles.
You can and should (my opinion) add a partition for a refugium.

Anything in place of bio-balls acts as the same thing because the conditions are still the same...A wet/dry environment. The bio-balls themselves aren't the problem but where they are placed. If you were to put live rock in place of the bio-balls with water trickling over them, you'd be in the same boat so as suggested, best bet is to remove the bio-balls (if not going fish only) and convert the wet/dry into a sump/fuge where you don't have a wet/dry environment which could cause any potential issues down the road. Just my 2 cents

LOL!!! Sorry :lol:
If there's room in the sump to partition off an area for live sand or live rubble rock, that's always going to be submerged, that'd make a great refugium. However, as Krish said, if it's an area where the substrate will get air, it'll still be a nitrate factory.
