[Tom-Kat]

I have a 29 gallon biocube and i know u guys have probly had this question aked before but should i take the bioballs out and put crushed live rock there??

Yes. The bioballs simply collects detritus and turns into a nitrate factory.

I always love that answer. It seems to me that if it is simply a matter of collecting detritus that bio balls and live rock rubble will have the same effect. There is no magical transportation field in the live rock rubble that makes the detritus disappear.

My understanding of the real reason is that the bio balls have no oxygen free zone where the bacteria that breakdown nitrates to nitrogen can live. The bacteria that live in bioballs can only break it down to nitrates and not completely break it down like the bacteria in live rock can.
