Altoona, PA tap water

Supplied by Altoona Water Authority. Here's what its water means for your fish.

Disinfectant

Chlorine

Your water is treated with chlorine. It slowly gases off from standing water, and any water conditioner removes it.

Safety for fish and shrimp

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)

Not detected (Low)

Not detected in testing, so water changes lower your tank's nitrate well.

From EPA monitoring data (2012–2019).

Chlorine or chloramine at the tap

0.5–1.3 ppm

Typical 0.9 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).

Water chemistry

General hardness

Not published yet

We haven't found this number yet. A drop test kit gives you your exact reading.

Little buffering. pH can drop quickly between water changes, especially with CO₂ or an older tank.

From EPA monitoring data (2012–2019).

pH

7.6–8.3

Typical 7.7

Most community fish do well here. Stable water matters more than the exact number.

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.
