I guess Id better further explain my thoughts.
Live rock does not produce Nitrates. It helps reduce them. I see the live rock as a place where bacteria lives so it can break down nitrates as part of the overall denitrification process in our tanks.
Bio-balls collect nitrate on them where it can be manually removed by the aquarist instead of the bacteria doing the job.
What I liked about Williams thoughts was (and I agree) with limited space in our sumps the, sand, "biosediment", and cheato are much more effective at reducing nitrates than LR stuffed in our sumps and offer other added benefits to the tank as well.
