No.  Chloramine is made of chlorine and ammonia.  A certain percentage of it 
naturally breaks down into the two main components, until it reached what I 
think the chemically enlightened call "equilibrium".  Then the chlorine 
dissipates, and the ammonia is removed by your plants and/or biological 
filter.  This takes the "equilibrium" away, so more chloramine breaks down.  
Then more dissipates/gets removed, then more breakes down.  It isn't in a 
staggered process like I'm compelled here to describe it.  It is a continuous 
reaction, or perhaps chain reaction.  I've lived where there have been 
chlorine, and where there has been chloramine.  It has been close to 20 years 
since I have used any kind of de-chlorinating agent.  I let new tanks stand 
overnight, and anytime I make a water change over 30%, I have fresh "aged" 
water standing by.

If the chlorine/chloramine threat were as great as the makers of Novaqua want 
you to think, the makers of the Python No-Spill Clean and Fill would have 
gone under a ling time ago.  This handy product lets you put water into your 
tank from a kitchen sink or a garden spigot.  The chlorine/ goes in right 
with the water, and by next day, it's all gone.  Chloramine takes a little 
longer, but it still removes itself.
