Cedar City, UT tap water
Supplied by Cedar City Waterworks. 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 (2016).
Nitrate (NO₃)
1.3–4 ppm (Low)
Typical 1.3 ppm
Low, so water changes lower your tank's nitrate well.
From EPA monitoring data (2012–2019).
Chlorine or chloramine at the tap
0.7 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.
