Woodfin, NC tap water
Supplied mostly by Woodfin Sanitary Water and Sewer, 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 EPA monitoring data (2013).
Nitrate (NO₃)
Not detected (Low)
Not detected in testing, so water changes lower your tank's nitrate well.
From EPA monitoring data (2012–2019).
Copper at home taps (first draw)
0.06–0.36 ppm (Low)
The 90th percentile of first-draw samples from homes: water that sat in household pipes for at least six hours.
Low. Water that sits in household pipes overnight can carry more than this.
Published by your utility: City of Asheville's 2025 water quality report.
Chlorine or chloramine at the tap
0.3–1.9 ppm
Typical 1.2 ppm
At tap levels, chlorine and chloramine are toxic to fish, shrimp and the bacteria in a filter. Water conditioners are made for this range.
Published by your utility: City of Asheville's 2025 water quality report.
Water chemistry
General hardness
6 ppm
Soft. Good for tetras, rasboras and most shrimp. Livebearers, snails and African cichlids prefer harder water.
Published by your utility: City of Asheville's 2025 water quality report.
Carbonate hardness (alkalinity)
4–24 ppm
Typical 4 ppm
Little buffering. pH can drop quickly between water changes, especially with CO₂ or an older tank.
From EPA monitoring data, measured before treatment; City of Asheville's 2025 water quality report (2012–2025).
pH
7.1–7.6
Typical 7.1
Most community fish do well here. Stable water matters more than the exact number.
