I just bought an ammonia alert and it has been at a grey setting for days. What does that mean?
The greyish color indicates the “Alarm” state of ammonia. Was it grey or yellow when you took it out of the packge and placed it in the tank? If it was yellow when you put it in and is now “grey” then that means you have a high level of ammonia and should do a water change very soon or treat with our AmGuard if a water change is not feasible within 24 hours. Q: I bought an Ammonia Alert but mine does not have the dark yellow, blue and other colors as the one on your website. Mine had pale yellow, light green, light aqua and dark purple colors. Is mine too old to work? Can or should I get a replacement one? A: Yours is actually the latest one. All the colors are the same except for the “alarm” color. Both are correct colors within the “alarm” range (transition between green to purple) but the greyish color that it was before represented a smaller range of that transition whereas the light aqua color represents a larger range so it is the color more commonly seen in that range.
