University Place, WA tap water
Supplied by City of Tacoma Water Division. Here's what its water means for your fish.
Disinfectant
Chlorine
Your water is treated with chlorine. It slowly gases off from standing water, and any water conditioner removes it.
Safety for fish and shrimp
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)
18–44 ppm (Worth knowing)
Typical 18 ppm
Water changes can't take your tank's nitrate below this level.
Published by your utility: City of Tacoma Water Division's 2025 water quality report.
Chlorine or chloramine at the tap
0.3–1.7 ppm
Typical 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.

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.
