Aquaclear 50 setup

I have the 50 and the 110 now, AC makes a good bio filtration bag and a very nice sponge, i would keep that and add anything you want, you can buy floss at a hobby shop or walmart for less and just cut it to size.
 
coarse sponge on bottom, finer sponge, polyfil, bio-media on top.
