Re: [Killietalk] Thiosulfate de-chloroamine

Hi john,

I understand that they use it and why they use it.  What i found 
funny was that they insisted they did not add chloramine to the water 
but chlorine and ammonia gives you chloramines.  Most municipalities 
are adding the two together to make their chloramines rather than 
adding chloramines directly.  So when they say they do not add 
chloramines, it does not mean you do not have them in your water. 
Also, some water sources, especially those from surface water, can be 
high in ammonia due to runoff from farms, etc. so you can still have 
chloramines.  It just means that some people need to take additional 
steps to be careful.
