No joke: I've used all plastic hair rollers in large filter units without problems.  They're much cheaper!  You can cut them in half to fit more into a given area..they pack closer that way.

Other than sand there is not much that can give you more Sq. ft of surface area than a cubic ft of oyster shell, and the bacteria that you  need to grow is a surface growing bacteria,the oyster shells help keep your PH balanced
