Midland, TX tap water

Supplied by City of Midland Water Purification Plant. 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 0.6 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

0.01–1.34 ppm (Worth knowing)

Typical 0.6 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 City of Midland Water Purification Plant reports (2025).

Nitrate (NO₃)

0.9–5.4 ppm (Low)

Typical 5.4 ppm

Water changes can't take your tank's nitrate below this level.

Copper at home taps (first draw)

0.01–0.62 ppm (Worth knowing)

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

Shrimp and snails are sensitive to copper. Water that sits in household pipes picks up the most; it drops once the tap has run for a minute.

Chlorine or chloramine at the tap

0.1–5.5 ppm

Typical 2.4 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.
