Inglewood, CA tap water
Supplied mostly by Inglewood- City, Water Dept., plus 1 other utility. Here's what the 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 0.58 ppm of ammonia here. Some utilities switch to plain chlorine for a few weeks a year.
Safety for fish and shrimp
Ammonia (with conditioner)
Estimate0.02–1.09 ppm (Worth knowing)
Typical 0.58 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 Golden State Water Company (GSWC) 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 (2018–2019).
Nitrate (NO₃)
Up to 2.9 ppm (Low)
Typically not detected
Not detected in testing, so water changes lower your tank's nitrate well.
From EPA monitoring data; Metropolitan Water Dist. of So. Cal., which supplies Golden State Water Company (GSWC) (2018–2026).
Copper at home taps
0.06–0.12 ppm (Low)
Typical 0.06 ppm
Low. Water that sits in household pipes overnight can carry more than this.
From California Water Board lab results; Golden State Water Company (GSWC)'s 2025 water quality report (2023–2025).
Chlorine or chloramine at the tap
0.1–4.5 ppm
Typical 2.4 ppm
