Jackson, MS tap water

Supplied by City of Jackson. 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 about 0.27 ppm of ammonia here. Some utilities switch to plain chlorine for a few weeks a year.

Safety for fish and shrimp

Ammonia (with conditioner)

Estimate

0.01–1.31 ppm (Low)

Typical 0.27 ppm

This is what a conditioner frees when it breaks the chloramine apart. A cycled filter clears it within a day.

Estimated from the chloramine level City of Jackson reports (2025).

Nitrite (NO₂)

Up to 0.18 ppm (Worth knowing)

Typical 0.18 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.

Published by your utility: City of Jackson's 2025 water quality report.

Nitrate (NO₃)

1.3 ppm (Low)

Low, so water changes lower your tank's nitrate well.

Published by your utility: City of Jackson's 2025 water quality report.

Chlorine or chloramine at the tap

0.1–5.4 ppm

Typical 1.1 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

58 ppm

Soft. Good for tetras, rasboras and most shrimp. Livebearers, snails and African cichlids prefer harder water.

Published by your utility: City of Jackson's website.

Carbonate hardness (alkalinity)

14 ppm

Little buffering. pH can drop quickly between water changes, especially with CO₂ or an older tank.
