Verdi, NV tap water
Supplied mostly by Verdi Meadows Utility Company Inc, plus 1 other utility. Here's what the water means for your fish.
Disinfectant
Chlorine or chloramine
Utilities here use chlorine or chloramine, depending on which one serves your address. Chlorine slowly gases off from standing water; chloramine doesn't.
Safety for fish and shrimp
Ammonia (with conditioner)
Estimate0.05–0.49 ppm (Low)
Typical 0.27 ppm
This is what a conditioner frees when it breaks the chloramine apart. A cycled filter clears it within a day.
Estimated from the chloramine level Truckee Meadows Water Authority reports (2025).
Nitrite (NO₂)
Not detected (Low)
Not detected in testing, so any nitrite in your tank comes from the tank itself.
From EPA monitoring data (2012–2019).
Nitrate (NO₃)
Up to 12 ppm (Low)
Typically not detected
Not detected in testing, so water changes lower your tank's nitrate well.
From EPA monitoring data (2012–2019).
Chlorine or chloramine at the tap
0.2–2 ppm
Typical 1.1 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.
Published by your utility: Truckee Meadows Water Authority's 2025 water quality report.

Our data comes from public records and is still incomplete. Many utilities don't publish every number, so we're adding more all the time. Your city's range is a starting point: testing your own tap is the only way to know exactly what's in it.
