Savannah, GA tap water
Supplied by City of Savannah Water Supply and Treatment Department. 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 0.49 ppm of ammonia here. Some utilities switch to plain chlorine for a few weeks a year.
Safety for fish and shrimp
Ammonia (with conditioner)
Estimate0.05–0.49 ppm (Low)
Typical 0.49 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 Savannah Water Supply and Treatment Department reports (2024).
Nitrate (NO₃)
Up to 1.2 ppm (Low)
Typical 1.2 ppm
Low, so water changes lower your tank's nitrate well.

Copper at home taps (first draw)
0.01–0.22 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.

Chlorine or chloramine at the tap
0.2–2 ppm
Typical 2 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.
