If you're like me, if it's a pain to do you won't do it
Refractometers are better than hydrometers but kind of a PITA.

perhaps you could try a colourimetric method. The Hach Colorimeter has a relatively easy-to-use, pre-packaged test kit for Zinc as well as other ions. Might have to check the details to see if other metal ions will interfere with the results tho

Hmm, I'd be shocked if one of us discovered a substance we could get at home that would create an as-of-yet-undiscovered precipitation reaction that would precipitate chloramine out of water! The reaction with citric acid you mentioned, is another one I now remember I've heard. All the points you make are right on, so if you figure something out, let us know! BUT the first step in my mind is finding a way to verify any potential results, so we're back to a cost effective way of measuring chloramine levels in a given water sample.

The cheap test strips for drinking water and aquariums seem to only test for chlorine (http://www.amazon.com/dp/B000FBMAVQ/)($13), and the expensive ones seem to indicate they CAN be calibrated to check for chloramine (http://www.amazon.com/dp/B00I4TFU1I/) ($1,099). This seems made specifically to test for chloramine, but it's unavailable (http://www.amazon.com/dp/B00R3EF7ZY/).

I'll bet small quantities of citric acid are fine, and small amount of humic acids are definitely beneficial (humic acid is naturally occurring in compost and is great for soil). How much is too much, idk, since I don't add any directly/intentionally.
