Sherrelwood, CO tap water
Part of Sherrelwood is supplied by Crestview WSD. Here's what its water means for your fish.
Disinfectant
Chloramine
Utility water here is treated with chloramine. Unlike chlorine, it doesn't gas off when water sits out, and many pitcher and fridge filters aren't rated to remove it. Conditioners that list chloramine on the label break it apart, which frees a little ammonia. Some utilities switch to plain chlorine for a few weeks a year.
