Hollywood, FL tap water
Supplied by City of Hollywood. 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
Nitrite (NO₂)
0.09–0.11 ppm (Worth knowing)
Typical 0.1 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)
0.3–0.4 ppm (Low)
Typical 0.3 ppm
Low, so water changes lower your tank's nitrate well.
From EPA monitoring data (2012–2019).

Our data comes from public records and is still incomplete. Many utilities don't publish every number, so we're adding more all the time. Your city's range is a starting point: testing your own tap is the only way to know exactly what's in it.
