I haven't been using any activated carbon, for a while now, mainly due to being too lazy to order some online for my cannister, partly due to having read (on another site) "that it takes out nutrients that the plants need". I am skeptical of that statement, since I had it in the filter originally and the plants grew just fine.
What exactly is the role of activated carbon in a planted tank? Is it a benefit or a hindrance?
