Canby, MN tap water
Supplied by Canby. 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
Nitrate (NO₃)
Area estimate0.1–43 ppm (Low)
Typical 0.5 ppm
Low, so water changes lower your tank's nitrate well.
Area estimate from nearby wells: USGS well samples in your county (2009).
Chlorine or chloramine at the tap
0.1–1.4 ppm
Typical 0.9 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 (2012–2019).
Water chemistry

Area estimate377–829 ppm
Typical 626 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 (2009–2011).
Carbonate hardness (alkalinity)
Area estimate355–396 ppm

Strong buffering. pH stays steady and hard to lower without RO water.
Area estimate from nearby wells: USGS well samples in your county (2009).
pH
7.5–7.6
