....I would take them out and replace it with some LR. In the long run it will be better for your tank.

I used to have Bio-balls in my sump and after about 3 months I decided to take them out and replace them with LR I saw just how filthy they can get.

there are also live rock under the bioballs. but i think i will take them out.

Its just the fact that the bio-balls tend to hold onto garbage that gets sucked down your overflows. Taking them out is just a better way of keeping a tank I think.

I'd just take out everything in that section and leave it empty. Any place that can trap detritus is likely to cause trouble.
