Killeen, TX tap water

Supplied by City of Killeen. Here's what its 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 0.49 ppm of ammonia here. Some utilities switch to plain chlorine for a few weeks a year.

Safety for fish and shrimp

Ammonia (with conditioner)

Estimate

0.12–0.88 ppm (Low)

Typical 0.49 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 of Killeen reports (2025).

Nitrate (NO₃)

1.5 ppm (Low)

Low, so water changes lower your tank's nitrate well.

Published by your utility: City of Killeen's 2025 water quality report.

Copper at home taps (first draw)

Up to 0.14 ppm (Low)

The 90th percentile of first-draw samples from homes: water that sat in household pipes for at least six hours.

Low. Water that sits in household pipes overnight can carry more than this.

Chlorine or chloramine at the tap

0.5–3.6 ppm

Typical 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.
