Coachella, CA tap water
Supplied mostly by Coachella Water Authority, plus 1 other utility. 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 (2024–2025).
Nitrate (NO₃)
Up to 5.8 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; California Water Board lab results (2023–2026).
Copper at home taps
Up to 0.02 ppm (Low)
Typical 0.02 ppm
Low. Water that sits in household pipes overnight can carry more than this.

Water chemistry
General hardness

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