Sump & Live Rock

I have a sump that I am removing the bio balls. Any reason I can't put some spare live rock in the sump once it's empty?

Or is there something better I should put down there? Maybe a fish? I know some of our club members keep fish in theirs! ;)
 
Stacey LR makes a very good bio-filter in the sump. It will become very white but is easy to color up again if you want to use it in another setup.
