Sunnyside-Tahoe City, CA tap water
Supplied mostly by Tahoe City PUD - Main, plus 2 other utilities. 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
Nitrate (NO₃)
Up to 1 ppm (Low)
Typically not detected
Not detected in testing, so water changes lower your tank's nitrate well.
From California Water Board lab results, measured before treatment (2023–2025).
Copper at home taps
0.07–0.15 ppm (Low)
Typical 0.08 ppm
Low. Water that sits in household pipes overnight can carry more than this.
From California Water Board lab results (2023–2026).
Water chemistry
General hardness
48–89 ppm
