Holt, MI tap water
Supplied by Lansing Board of Water & Light. Here's what its 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 about 0.54 ppm of ammonia here. Some utilities switch to plain chlorine for a few weeks a year.
Safety for fish and shrimp
Ammonia (with conditioner)
Estimate0.1–0.68 ppm (Worth knowing)
Typical 0.54 ppm
This is what a conditioner frees when it breaks the chloramine apart. A cycled filter clears it within a day; a big water change in a new or very small tank adds more of it at once. Some conditioners also bind ammonia for a day or so.
Estimated from the chloramine level Lansing Board of Water & Light reports (2024).
Nitrate (NO₃)
Area estimateUp to 7.3 ppm (Low)
Typical 0.4 ppm
Low, so water changes lower your tank's nitrate well.
Area estimate from nearby wells: USGS well samples in your county (2015–2017).
Chlorine or chloramine at the tap
0.4–2.8 ppm
Typical 2.2 ppm
At tap levels, chlorine and chloramine are toxic to fish, shrimp and the bacteria in a filter. Water conditioners are made for this range.
