I can tell you that it really does. Because of that my tank is clean all the time. I spend 5 minutes every week to take out the poop that collects on the bottom, but it's nothing compared to the water changes I used to do when I had rocks in there. And I found that with with gravel and even river rocks, you can never completely clean the bottom because something is always hiding underneath a rock or whatnot. I even changed my fish tank into a bare bottom.
