I purchased this sump in a larger size. I will be tossing the bio-balls & removing the eggcrate. I intended to fill that chamber with LR
rubble. I have one concern though; the acrylic panal on the right side of the bio-balls has a wide slot 6"-7" above the bottom. The water that normally lies beneath the bio-balls does not move or flow. Can my LR
rubble be down in the bottom without dying off?
If not; how can I remedy this situation?
