Disinfectant
Not confirmed
We couldn't confirm how utility water here is disinfected. US utilities use chlorine or chloramine, and chloramine doesn't gas off when water sits out. Private wells aren't treated by a utility, so there's no chlorine or chloramine unless a treatment system adds it.
Safety for fish and shrimp
Nitrate (NO₃)
8.9–12 ppm (Worth knowing)
Typical 10 ppm
Water changes can't take your tank's nitrate below this level.
From California Water Board lab results, measured before treatment (2023–2025).
Copper at home taps
0.01 ppm (Low)
Low. Water that sits in household pipes overnight can carry more than this.
