Hopwood, PA tap water
Supplied mostly by PA-American Water- Uniontown, plus 1 other utility. Here's what the water means for your fish.
Disinfectant
Chlorine or chloramine

Safety for fish and shrimp
Ammonia (with conditioner)
Estimate0.24–0.45 ppm (Low)
Typical 0.35 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 PA-American Water- Uniontown reports (2016–2019).
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)
Supplier's figure1.7–4 ppm (Low)
Typical 2.9 ppm
Low, so water changes lower your tank's nitrate well.
