Do you have chloramine in the source water?

I don't know about that but i think the anti chlorine Also removes chloramines

Yes, but ammonia is separated (in the chloramine) and apparently often shows as a very low level. So if your water authority adds chloramine, this could be the "ammonia" you are testing. In which case you can ignore it.

Colin knows more about this chemistry and has posted about this elsewhere.
