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.

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.
