For some reason our tap water has ammonia in it. However, my RODI system doesn't seem to be removing it, even after I've replaced and flushed out the filter. I know the test kit is working because I tested another water source, and there is no Ammonia. I've been using prime to detoxify it (btw can anyone confirm that prime actually detoxifies ammonia?), but I want to not have to worry about it anymore. Does anyone know why the RODI is not removing the ammonia, or what I can do to remove it?
