In my sump I have section 1 with bio balls, 2 I a refugium, 3 is empty and 4 is the return pump. I have heard bad things about bio balls would it be beneficial to remove the bio balls and add more live rock or maybe move the bio balls to the 3rd section and put live rock inthe first section or even put something else in completely different? Any tips would be appreciated
