Bioballs?

i would take them out and replace them with live rock rubble because in my tank they coused my nitrites to spike.
 
I have bioballs also. They are on tope of the bag of tubes which sits on top of the carbon bag.
I should take them out and put LR rubble on top of the bag of tubes? Base rock or true live rock?
 
Remove the bioballs; if you keep an ample amount of LR & LS in the main portion, then adding rubble is rather moot.
 
I asked in the other thread about the size of rubble. Does anyone have a size to describe?
