Fullerton, PA tap water

Supplied mostly by Whitehall Twp Authority, 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)

Estimate

0.56–0.8 ppm (Worth knowing)

Typical 0.72 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 Whitehall Twp Authority 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)

Up to 16 ppm (Worth knowing)

Typical 13 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

1–3.3 ppm

Typical 3 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

Area estimate

132–155 ppm

Typical 134 ppm

Moderately soft to medium. Suits most community fish and plants.

Area estimate from nearby wells: USGS well samples in your county (2000–2023).

Carbonate hardness (alkalinity)

30 ppm

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

From EPA monitoring data, measured before treatment (2012–2019).

pH

Area estimate

6.4–7.6

Typical 7.2

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

Area estimate from nearby wells: USGS well samples in your county (2000–2023).

Total dissolved solids

Area estimate

181–390 ppm

Typical 192 ppm

A rough measure of everything dissolved in the water. RO water reads near 0, so TDS is a quick way to compare waters.

Area estimate from nearby wells: USGS well samples in your county (2000–2023).
