Southmont, NC tap water

Supplied by Davidson Water Inc. 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 EPA monitoring data (2017–2019).

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)

0.05–0.28 ppm (Worth knowing)

The 90th percentile of first-draw samples from homes: water that sat in household pipes for at least six hours.

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.

Chlorine or chloramine at the tap

0–2.4 ppm

Typical 1.4 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.

  • Davidson Water Inc adds phosphate to protect pipes. It can feed algae in tanks without much plant growth.
  • Davidson Water Inc softens its water at the plant, so it may be softer than the local groundwater.
