are bioballs beneficial in a SW set up, or not? I've been reading mixed reports. I have them in the sump where the overflow drains into it, and also in my overflow box. Is this a waste of time/space, or are they beneficial in those areas.
p.s. i have the display tank's drain line ending with a drilled pvc pipe into the sump, which drips over the bioballs. about 85% of the bioballs are submerged, if that helps.
