Camp Pendleton South, CA tap water
Supplied by Camp Pendleton (South). 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 (2023–2026).
Nitrate (NO₃)
0.2–8 ppm (Low)
Typical 1.6 ppm
Low, so water changes lower your tank's nitrate well.
From California Water Board lab results (2023–2026).
Copper at home taps
0.15 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 (2025).
Water chemistry
General hardness
110–370 ppm
Typical 338 ppm
Hard. Ideal for livebearers and African cichlids. Soft-water species may struggle to breed.

Strong buffering. pH stays steady and hard to lower without RO water.
From California Water Board lab results (2023–2026).
pH

From California Water Board lab results (2023–2026).
Total dissolved solids
280–770 ppm
Typical 718 ppm
A rough measure of everything dissolved in the water. RO water reads near 0, so TDS is a quick way to compare waters.
