Bellevue, NE tap water
Supplied by Metropolitan Utilities District (M.U.D.). Here's what its water means for your fish.
Disinfectant
Chloramine
Your water is treated with chloramine. Unlike chlorine, it doesn't gas off when water sits out, and many pitcher and fridge filters aren't rated to remove it. Conditioners that list chloramine on the label break it apart, which frees a little ammonia. Some utilities switch to plain chlorine for a few weeks a year.
Safety for fish and shrimp
Nitrate (NO₃)
2.4–14 ppm (Worth knowing)
Typical 14 ppm
Water changes can't take your tank's nitrate below this level.
Published by your utility: Metropolitan Utilities District (M.U.D.)'s 2025 water quality report.
Copper at home taps (first draw)
Up to 0.22 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.

137–223 ppm
Typical 154 ppm
Moderately hard. Great for livebearers, and most community fish adapt.

Carbonate hardness (alkalinity)
59–227 ppm

pH
8.8–9.2
Typical 9
Alkaline. Many utilities raise pH to protect pipes. Stability matters more than the exact number.

Total dissolved solids
112–515 ppm
Typical 112 ppm
A rough measure of everything dissolved in the water. RO water reads near 0, so TDS is a quick way to compare waters.
