Phoenix Lake, CA tap water
About 49% of Phoenix Lake is inside a utility's service area. Homes outside it likely use private wells, which no utility tests.
Disinfectant
Chlorine
Utility water here is treated with chlorine. It slowly gases off from standing water, and any water conditioner removes it. 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)
Up to 9.2 ppm (Low)
Typical 0.6 ppm
Low, so water changes lower your tank's nitrate well.
From California Water Board lab results, measured before treatment (2023–2026).
Copper at home taps
0.1–0.21 ppm (Worth knowing)
Typical 0.13 ppm
Shrimp and snails are sensitive to copper. Water that sits in household pipes picks up the most; it drops once the tap has run for a minute.
From California Water Board lab results (2023–2026).
Water chemistry
General hardness
52–311 ppm
Typical 203 ppm
Moderately hard. Great for livebearers, and most community fish adapt.
From California Water Board lab results, measured before treatment; Belleview Oaks Mutual Water Co's calcium and magnesium readings, measured before treatment (2024–2025).
Carbonate hardness (alkalinity)
118–298 ppm
Typical 199 ppm
Strong buffering. pH stays steady and hard to lower without RO water.
From California Water Board lab results, measured before treatment (2024–2025).
pH
6.1–8
Typical 6.9
Most community fish do well here. Stable water matters more than the exact number.
From California Water Board lab results, measured before treatment (2024–2025).
Total dissolved solids
116–340 ppm
Typical 210 ppm
A rough measure of everything dissolved in the water. RO water reads near 0, so TDS is a quick way to compare waters.
From California Water Board lab results, measured before treatment (2024–2025).
