It can't hurt. As to weather it will help much... hard to say. Bio media is a good thing and with high loads you need a lot. but i think a lot of people worry too much about it. I figure as long and you never see any ammonia or nitrite you have enough bio media.
I am planning on setting up a sump soon, i was thinking about adding an air stone (actaully a felixable bubble wand) to the bio media area because i am planning on having most the media covered with water to maximize my water volume. The air stone should reaise the effiency of the BB so i don't need as much bio media.
