Now that I think of it and check other sources, the statement about the chloramine being removed by the DI resin does not agree with any of the other info I have seen. Other sources indicate that (while I have long known that deionization beaks down buffers and softens the water), chlorine and chloramine are removed by these newer types of carbon block filters:

The Filter Guys, another supplier of RO/DI & filtration. equipment also seem to be in agreement with this as well. I am currently inclined to agree with them and the aforementioned article because, at any rate, my professional grade Salifert ammonia test indicates zero ammonia in the output of my unit (which at present has no DI stage). Once I further verify the effectiveness of this newer type cartridge I am now using with chlorine & chloramine tests, I will post my findings and henceforth use cartridges obtained from The Filter Guys supply house.
Since the buffering effect of my locale's relatively hard water is of no consequence - as it would be were I trying to operate a freshwater aquarium at a neutral PH - I am not at all certain whether addition of a DI stage would be of any benefit to me. Having obtained a report from my city's water department, I see nothing problematic in our water to be removed other than chloramine and maybe a little manganese.
