New Haven, IN tap water
Supplied mostly by New Haven Water Department, 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 0.5 ppm of ammonia here. Some utilities switch to plain chlorine for a few weeks a year.
Safety for fish and shrimp
Ammonia (with conditioner)
Estimate0.01–0.5 ppm (Low)
Typical 0.5 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 Utilities - Fort Wayne reports (2024).
Nitrite (NO₂)
Not detected (Low)
Not detected in testing, so any nitrite in your tank comes from the tank itself.
Published by your utility: City Utilities - Fort Wayne's 2024 water quality report.
Nitrate (NO₃)
Supplier's figureUp to 20 ppm (Worth knowing)
Typical 20 ppm
Water changes can't take your tank's nitrate below this level.
From the utility that supplies yours: Fort Wayne - 3 Rivers Filtration Plant, which supplies New Haven Water Department; City Utilities - Fort Wayne's 2024 water quality report.
Copper at home taps (first draw)
Up to 0.15 ppm (Low)
