Hayti, PA tap water
Supplied mostly by Pennsylvania American Water – Coatesville, plus 1 other utility. Here's what the water means for your fish.
Disinfectant
Chlorine or chloramine
Utilities here use chlorine or chloramine, depending on which one serves your address. Chlorine slowly gases off from standing water; chloramine doesn't.
Safety for fish and shrimp
Ammonia (with conditioner)
Estimate0.38–0.71 ppm (Worth knowing)
Typical 0.54 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 Pennsylvania American Water – Coatesville reports (2012–2019).
Nitrite (NO₂)
Not detected (Low)
Not detected in testing, so any nitrite in your tank comes from the tank itself.
From EPA monitoring data (2012–2019).
Nitrate (NO₃)
6–14 ppm (Worth knowing)
Typical 14 ppm
Water changes can't take your tank's nitrate below this level.
From EPA monitoring data (2012–2019).
Chlorine or chloramine at the tap
1.5–2.9 ppm
Typical 2.2 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.
From EPA monitoring data (2012–2019).
