Bradenton, FL tap water
Supplied mostly by City of Bradenton, plus 1 other utility. Here's what the 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 0.8 ppm of ammonia here. Some utilities switch to plain chlorine for a few weeks a year.
Safety for fish and shrimp
Ammonia (with conditioner)
Estimate0.8–1.29 ppm (Worth knowing)
Typical 0.8 ppm
This is what a conditioner frees when it breaks the chloramine apart. A cycled filter clears it within a day; a big water change in a new or very small tank adds more of it at once. Some conditioners also bind ammonia for a day or so.
Estimated from the chloramine level Manatee County Utilities Department reports (2025).
Nitrite (NO₂)
Up to 0.3 ppm (Worth knowing)
Typical 0.15 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.
From EPA monitoring data (2012–2019).
Nitrate (NO₃)
Up to 1.2 ppm (Low)
Typical 0.1 ppm
Low, so water changes lower your tank's nitrate well.
From EPA monitoring data; Manatee County Utilities Department's 2025 water quality report (2012–2025).
Copper at home taps (first draw)
0.18 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 your utility: Manatee County Utilities Department's 2025 water quality report.
Chlorine or chloramine at the tap
3.3–5.3 ppm
Typical 3.3 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.
