Arden-Arcade, CA tap water

Supplied mostly by Sacramento Suburban Water District, plus 5 other utilities. Here's what the 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 California Water Board lab results; EPA monitoring data (2016–2026).

Nitrate (NO₃)

Supplier's figure

Up to 19 ppm (Low)

Typical 2.2 ppm

Low, so water changes lower your tank's nitrate well.

From the utility that supplies yours: City of Sacramento Main and San Juan Water District, which supplies Sacramento Suburban Water District; City of Sacramento Main, which supplies Cal Am - Arden; California Water Board lab results, measured before treatment; Sacramento County Water Agency (SCWA)'s 2025 water quality report; EPA monitoring data (2015–2026).

Copper at home taps

0.05–0.09 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; Sacramento County Water Agency (SCWA)'s 2025 water quality report (2023–2025).

Chlorine or chloramine at the tap

0.1–2 ppm

Typical 1.3 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.

Published by your utility: Sacramento County Water Agency (SCWA)'s 2025 water quality report.

Water chemistry

General hardness

Supplier's figure

9–250 ppm

Typical 50 ppm

Supplier's figure

14–200 ppm

Typical 57 ppm

Moderate buffering. pH should stay fairly steady.

Supplier's figure

7.2–8.4

Typical 7.8

31–420 ppm

Typical 118 ppm

A rough measure of everything dissolved in the water. RO water reads near 0, so TDS is a quick way to compare waters.
