Interesting! I better contact the city and ask if it's used in BC. Funny this was just mentioned on Mr Saltwater Tank passed Friday.

Victoria uses chloramine for it's water. I've never addressed it in my system though....

I think prime takes care of ammonia, chlorine and chloramine as well, but I could be wrong, I know it says a few things like that on the label

Yeap Edmonton definitely does. Most places do but Calgary doesn't as of yet as far as I know. But for the record my tanks always did fine in Saskatoon.

It doesn't disappear tho. It's converted to something less dangerous

ahhh, I see lol. I wonder if putting prime in it the bubbling an airstone like you would for chlorine if that would take care of the rest? probably not haha

For Metro Vancouver (including Burnaby reefers), I found this posted by the government:

"Metro Vancouver draws its water from Capilano, Seymour and Coquitlam sources and distributes it through its waterworks systems to member municipalities after treatment. As a part of the provision for treating water, Metro Vancouver uses chlorine as a primary disinfectant for Seymour and Capilano source waters. Coquitlam source water uses ozone and ultraviolet (UV) light as primary disinfectants. These source waters are subsequently
re-chlorinated at various regional secondary disinfection facilities installed in 1998. The disinfectant dosages are monitored at the regional chlorination facilities using on-line potentiometric chlorine analyzers.

The Seymour-Capilano Filtration Plant (SCFP) which is located near Rice Lake in the Lower Seymour Conservation Reserve went to full filtration on January 15th, 2010 and operated successfully throughout 2010. The Seymour source water is now be treated (filtration, corrosion control and disinfection) at SCFP and is conveyed by regional water mains to member municipalities for distribution to homes, businesses and industry. The primary disinfection facility at Seymour Falls Dam continued to operate until July 22, 2010.
Metro Vancouver discontinued chlorination of the Seymour source at Seymour Fall Dam on July 29th, 2010. When the twin tunnel component of the SCFP project is complete, the Plant will treat 1.8 billion litres of water from both the Seymour and Capilano sources. SCFP was constructed in the fall 2009, and is the largest of its kind in Canada. It includes the world’s largest ultraviolet disinfection system."

I called the city of Coquitlam and Metro water. They told me that they DO NOT use chloramine as a additive. The lady who answered the phone went on to tell me about how chloramine does produce naturally through the clean water process. I did look up the natural formation of chloramine. http://www.lenntech.com/processes/di...hloramines.htm
It seems that only thing will take out chloramine will be rox carbon in your ro system. I am not too sure if its gonna make a difference since my ro out always reads 0 ppm maybe I'll change my carbon filter to rox and see if it make any difference in the tank.

What is this special filter I need? I have a 5 stage system and seems to be working fine in edmonton here. I don't use any prime....

I had checked with the City of Calgary before I purchased my RO/DI unit to see if they used chloramine to treat the water. This is the information they gave me.

There are two treatment facilities for the City of Calgary. So it depends which part of the city you live in as to where your water is treated.

Bearspaw (from Bow River): Uses chlorine gas.
Glenmore (from Glenmore Resevoir): Uses sodium hypochlorite (NaOCl)
