Granger, IN tap water
Part of Granger is supplied by South Bend Water Utility, plus 1 other utility. Here's what its water means for your fish.
Disinfectant
Chlorine
Utility water here 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 (2014–2017).
Nitrate (NO₃)
Up to 29 ppm (High)
Typical 29 ppm
High for tap water. Water changes can't take your tank's nitrate below this level.
From South Bend Water Utility's 2024 water quality report; EPA monitoring data (2012–2024).
Copper at home taps (first draw)
0.17 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.
Published by the utility: South Bend Water Utility's 2024 water quality report.
Chlorine or chloramine at the tap
0.2–2.1 ppm
Typical 1 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.

Water chemistry
General hardness
282–470 ppm
Typical 369 ppm

Published by the utility: South Bend Water Utility's website.
Carbonate hardness (alkalinity)
230–378 ppm
Typical 294 ppm
Strong buffering. pH stays steady and hard to lower without RO water.
Published by the utility: South Bend Water Utility's website.
pH
7.1–7.9
Typical 7.4
Most community fish do well here. Stable water matters more than the exact number.

Total dissolved solids
369–735 ppm
Typical 535 ppm
A rough measure of everything dissolved in the water. RO water reads near 0, so TDS is a quick way to compare waters.
