I've updated this article from "Aquarium/Pond Answers"
Tap water in Aquarium/Pond; Chlorine/Chloramines, TDS, Vitamin C
Here is an excerpt:
Also note, Vitamin C (ascorbic acid/sodium ascorbate) is also an reasonable reducer (albeit not as strong as others at doses that do not affect pH dramatically), which also goes along with many of my points for a Reducing Redox.
In fact, Vitamin C in either Ascorbic Acid or Sodium Ascorbate can effectively lower chlorine or break the chloramine bond. Generally, approximately 2.5 to 2.8 parts of Vitamin C is required to neutralize 1 part chlorine
Be aware that Vitamin C, in particular in the form of ascorbic acid, can dramatically lower pH in normal doses to be effective.
Vitamin C may be a good choice for 25% water changes where its lower reduction abilities at safer pH doses might even be desired.
HOWEVER, in larger water changes or especially with chloramines, the undesirable drop in pH at doses required may make it a poor or even dangerous choice. Ascorbic Acid at doses that may be required will immediately reduce pH by 1.5 on the logarithmic pH scale (which can shock or even kill fish when this change happens suddenly, which it does). Sodium Ascorbate will change pH at doses required will immediately reduce pH by .5 (reference 1).
Nor is Vitamin C as a good a choice for long term Redox balance and reduction since it is a short term reduce
