Ruskin, FL tap water

Supplied mostly by Hillsborough County Water Resources, 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

0.01–1.65 ppm (Worth knowing)

Typical 0.92 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 Hillsborough County Water Resources reports (2025).

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 1.3 ppm (Low)

Typical 1.2 ppm

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

From Hillsborough County Water Resources' 2025 water quality report; EPA monitoring data (2012–2025).

Copper at home taps (first draw)

Up to 0.68 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.

Published by your utility: Hillsborough County Water Resources' 2025 water quality report.

Chlorine or chloramine at the tap

0–6.8 ppm

Typical 3.8 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.

Published by your utility: Hillsborough County Water Resources' 2025 water quality report.

Water chemistry

General hardness

Not published yet

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

Carbonate hardness (alkalinity)

Supplier's figure

98 ppm

Moderate buffering. pH should stay fairly steady.

From the utility that supplies yours: Tampa Bay Water Reg. Surface Water Plant, which supplies Hillsborough County Water Resources (2019).

pH

7.2–7.8

Typical 7.7

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

From EPA monitoring data (2012–2018).

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.
