You are correct. Carbon will remove the nutrients from the water column.

The ceramic rings are porous, and have a lot of surface area. The high surface area allows for a lot of room for beneficial bacteria to grow. In a sense I guess they do aid in removing the smell.

Have nothing but filter floss,ceramic rings, and bio balls in my filters.
