Personally, I dislike the ones with all the slime coat and anti-ammonia
proprietary ingredients.  I use the ones that contain just sodium
thiosulfate.  Two brands are Mardel's MarChlor and Wardley's ChlorOut.
These are 2-3 drops per gallon and cost me about $5/year even though
I do a lot of water changes.  Sodium thiosulphate reacts with chlorine
to eventually produce sodium ion, chloride ion and sulfate ion.  Sulfate 
is actually a plant nutrient, so no problem there.  It works on chloramine 
too.  The ammonia is immediately consumed by my plants, I suppose.

People who use pythons or hoses usually add the dechlorinator to the
tank before adding the new water.  The reaction is almost instantaneous.
