They better be, i just removed a full five gallon bucket of bioballs from my system based on "feedback" about them.
All of the detritus is gone in my sump and its functioning much better. I custom built a single 7inch sock for both overflows to pour into and i change it out every Monday and Thursday. I also ran my intake pump for my skimmer into that same holding chamber and the exhaust goes into the holding area where the return pumps are. The system is running MUCH better now. I have also added some rubble in the overflow area in the sump along with 1 hermit.
