Grandview, MO tap water

Supplied mostly by Jackson County Pwsd 1, plus 1 other utility. Here's what the water means for your fish.

Disinfectant

Chloramine

Your water 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.

Safety for fish and shrimp

Nitrate (NO₃)

7.1 ppm (Low)
