What about some Geos?
I have some in with my aro and they are always out...sifting away. They are great for finding any bits and pieces that fall to the bottom from the aro. I find they help prevent the bacteria in the gravel from turning anaerobic because they don't allow a lot of detruis to sit because they are constantly turning the gravel.
