 Yes, if you need it. Sometimes you do, other times you don't. My 180 had 0ppm/0ppm with no carbon dosing. I think if you have a fully loaded tank, the corals use up the excess. 
With my current tank, rock was leaching, so I found it useful. Once I rebuild next week, I won't dose unless/until I need to.
