Auburn Lake Trails, CA tap water

Supplied by Georgetown Divide PUD. 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

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 (2026).

Nitrate (NO₃)

0.2–0.4 ppm (Low)

Typical 0.3 ppm

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

From California Water Board lab results (2025–2026).

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 (2023).

Water chemistry

General hardness

8–11 ppm

Typical 10 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)

Not published yet

We haven't found this number yet. A drop test kit gives you your exact reading.

pH

6.9–7

Typical 6.9

Most community fish do well here. Stable water matters more than the exact number.

From EPA monitoring data, measured before treatment (2014–2018).

Total dissolved solids

19–20 ppm

Typical 20 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).
