Woodbury, MN tap water
Supplied by Woodbury. 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)
0.03–0.43 ppm (Worth knowing)
Typical 0.23 ppm
Some nitrite shows up in this tap water, which can happen in chloramine systems, and it goes into the tank with each water change.
From EPA monitoring data (2016–2017).
Nitrate (NO₃)
Area estimate0.7–31 ppm (Low)
Typical 9.2 ppm
Water changes can't take your tank's nitrate below this level.
Area estimate from nearby wells: USGS well samples in your county (2002–2018).
Chlorine or chloramine at the tap
0.4–0.8 ppm
Typical 0.5 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.
From EPA monitoring data (2017–2019).
Water chemistry
General hardness
Area estimate177–445 ppm
Typical 246 ppm
Hard. Ideal for livebearers and African cichlids. Soft-water species may struggle to breed.
Area estimate from nearby wells: USGS well samples in your county (2007–2018).
Carbonate hardness (alkalinity)
Area estimate144–341 ppm
Typical 224 ppm
Strong buffering. pH stays steady and hard to lower without RO water.
Area estimate from nearby wells: USGS well samples in your county (2007–2018).
pH
Area estimate6.5–7.6
Typical 7.2
Most community fish do well here. Stable water matters more than the exact number.
Area estimate from nearby wells: USGS well samples in your county (2002–2018).
Total dissolved solids
Area estimate49–585 ppm
Typical 286 ppm
A rough measure of everything dissolved in the water. RO water reads near 0, so TDS is a quick way to compare waters.
Area estimate from nearby wells: USGS well samples in your county (2003–2018).
- Woodbury adds phosphate to protect pipes. It can feed algae in tanks without much plant growth.
