Eldridge, CA tap water
Supplied by Valley of the Moon Water District. 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
Nitrate (NO₃)
Up to 16 ppm (Low)
Typical 2.2 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
0.12 ppm (Worth knowing)
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).
Water chemistry
General hardness
43–160 ppm
Typical 59 ppm
Soft. Good for tetras, rasboras and most shrimp. Livebearers, snails and African cichlids prefer harder water.
From California Water Board lab results, measured before treatment (2023–2026).
Carbonate hardness (alkalinity)
71–156 ppm
Typical 93 ppm
Moderate buffering. pH should stay fairly steady.
From California Water Board lab results, measured before treatment (2023–2026).
pH
6.9–7.4
Typical 7
Most community fish do well here. Stable water matters more than the exact number.
From California Water Board lab results, measured before treatment (2023–2026).
Total dissolved solids
178–287 ppm
Typical 193 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 (2023–2026).
