I built the same setup recently. I don't think standard carbon filters remove chloramine, however, some quick Googling showed that simple Vitamin C (i.e., Citric Acid) can break apart the chlorine and ammonia bond, which carbon can then filter out.
Alternately, you can find a catalyst carbon filter designed to remove chloramines.
