this seemed to be the bottom line for fish according to that pdf:
"Q: What are the methods for removing chloramine from fish aquariums?
A: Just as with chlorine, chloramine can harm saltwater and freshwater fish, reptiles, shellfish,
and amphibians that live in water, because they take chloramine directly into their bloodstream
through their gills. People and animals that don’t live in water can safely drink chloraminated
water because their digestive process neutralizes chloramine before it enters the bloodstream.
Effective procedures are available to remove chloramine and ammonia. Commercial
establishments and hobbyists involved in fish rearing need to take precautions to prevent losses.
There are two methods that can be used to remove or neutralize chloramine before adding
water to a fish tank, pond, or aquarium: (1) GAC filtration system specifically designed to remove
chloramine, or (2) conditioner or additive that contains a dechloraminating chemical for both
ammonia and chlorine. Products are available at local pet and aquarium supply stores.
Residential and commercial fish owners are advised to verify which method is best for them with
their pet store or aquatic/aquarium retailer.
If too much dechlorinating agent is added to the aquarium or pond water, it may bind up the
oxygen in the water. In this case, the fish may suffocate. It is important to carefully follow the label
instructions."

"Q: Can Vitamin C be used to remove chlorine and chloramine for bathing purposes?
A: Exposures via respiration do not occur from use of chloraminated drinking water. Based on
personal preference, some individuals may choose to reduce exposure to chlorine or chloramine.
Vitamin C (ascorbic acid) has recently been included in AWWA Standard (AWWA, 2005b) as one
of the methods for dechlorination of disinfected water mains. SFPUC and other utilities have used
Vitamin C for dechlorination prior to environmental discharges of chlorinated and chloraminated
water. Since ascorbic acid is weakly acidic, the pH of water may decrease slightly (Tikkanen et
al., 2001). Ascorbic acid has been used for a long time as one of the dechlorinating agents for
preservation of chlorinated or chloraminated water samples for laboratory analysis.
The removal of chloramine is not necessary from a public health perspective; however, some
customers may chose to remove either chlorine or chloramine for bathing purposes. There are no
NSF International certified point of use devices utilizing Vitamin C, however SFPUC determined
that 1000 mg of Vitamin C (tablets purchased in a grocery store, crushed and mixed in with the
bath water) remove chloramine completely in a medium size bathtub without significantly
depressing pH. Shower attachments containing Vitamin C can be purchased on the Internet, as
well as effervescent Vitamin C bath tablets. The 1000 mg effervescent Vitamin C tablets
dissolved readily without residue but may depress pH more than regular Vitamin C tablets
purchased in grocery stores.
Some shower attachments with Vitamin C marketed on the Internet
are effective in removing chloramine; however, the claims posted on the Internet as to their
replacement frequency appear to overestimate the duration when the shower attachment is
effective. There are reports of the benefits of Vitamin C for skin care (Griffith, 1998) and various
cosmetics are available in stores that contain Vitamin C. SFPUC does not recommend for
customers to use Vitamin C for bathing purposes and anyone desiring to do that should consult
with their physician."
and i think the doubts by the member on the seachem forum were handled quite well by the administrator although in the long run he's really just selling another seachem product.
i do see your points about vitamin c. i assume you've been using it? how's it working out for you? can you provide a dosage for aquarium use? the article seemed to focus on 1000mg FOR A BATHTUB. i'd say that's probably a little much for a w/c on 80 gallons worth of planted tanks. much less those that have smaller tanks.
