Searles Valley, CA tap water

Supplied by Searles Valley Minerals Operations Inc. 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 12 ppm (Low)

Typical 5.8 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

Not detected (Low)

Not detected in testing. Water that sits in household pipes overnight can still pick some up.

From California Water Board lab results (2024).

Water chemistry

General hardness

7–370 ppm

Typical 16 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).

Carbonate hardness (alkalinity)

86–180 ppm

Typical 120 ppm

Strong buffering. pH stays steady and hard to lower without RO water.

From California Water Board lab results, measured before treatment (2023).

pH

7.8–9.3

Typical 8.8

Alkaline. Many utilities raise pH to protect pipes. Stability matters more than the exact number.

From California Water Board lab results, measured before treatment (2023).

Total dissolved solids

230–1100 ppm

Typical 270 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).
