Does your Vero Beach tap water taste different this month? The city's Nov. 1–20 chlorine switch, explained

If your morning coffee or a glass of tap water tasted a little different this weekend, there may be a simple reason. The City of Vero Beach has changed how it disinfects its drinking water for a few weeks, as it does every year.

The switch started Nov. 1, 2026, and runs through Nov. 20. For most homes, the only change is a stronger chlorine taste or smell. But two groups need to act now: people who keep fish or ponds, and anyone who does kidney dialysis at home.

What the city is changing, and why

Most of the year, Vero Beach disinfects its water with chloramines. Chloramines are chlorine combined with a small amount of ammonia. The city's own water quality report lists chloramine disinfection as part of its normal treatment, along with lime softening and filtration.

For a few weeks each year, the city stops adding the ammonia. That leaves "free chlorine," which is plain chlorine without the ammonia attached. The city's notice, posted Oct. 2, calls this part of its annual maintenance.

Here are the dates and numbers from the city's notice:

• Nov. 1 through Nov. 20, 2026: the city uses free chlorine to disinfect drinking water.
• During that time, the water may contain up to 3.5 ppm (parts per million) of free chlorine at times.
• The water may contain free chlorine, ammonia or chloramines, in any combination.
• Nov. 21, 2026: the city starts adding ammonia again.
• For about a week after Nov. 21, water in parts of the system may contain both free and combined chlorine while older water in the pipes is replaced.

This notice comes from the City of Vero Beach water department. If your water bill comes from the city, it applies to you. If your water comes from Indian River County Utilities or a private well, this notice does not cover you. Check your bill if you are not sure.

Most homes: it is mostly about taste

Other Florida utilities that make the same kind of switch say people may notice a stronger chlorine taste or smell, and that this is normal. The City of Lake Worth Beach, for example, says the taste or odor poses no health risk.

If the taste bothers you, Lake Worth Beach suggests an easy fix: keep an open container of drinking water in the refrigerator for a few hours so the chlorine can fade. A pitcher on the top shelf works fine.

Fish tanks and ponds: treat every drop

This is the group that can lose something real. The U.S. Environmental Protection Agency says both chlorine and chloramine must be neutralized or removed before water goes into an aquarium. These chemicals can harm fish by entering their bloodstream through the gills. They can also stop the good bacteria a healthy tank needs from growing.

The EPA says tap water can be made safe for aquariums with products sold at aquarium supply stores. Lake Worth Beach adds two points that matter during a switch like this one. First, test the water before you add it to a tank or pond. Second, the product you use has to handle what is in the water now. Pet and fish stores sell additives with directions for removing free chlorine or chloramines. Read the label before you top off the tank.

Home dialysis: call your care team

The city's notice is written for dialysis providers. It says the temporary change "may affect dialysis operations" and patients in its service area.

The EPA explains why. Water used in a dialysis machine touches the blood directly, so chlorine and chloramine must be removed first. Removing free chlorine is not the same job as removing chloramine, so Lake Worth Beach tells home dialysis users to check with professionals. The EPA also says dialysis patients can safely drink chlorinated or chloraminated water. The issue is the machine, not the glass.

What to do this week

1. Check your water bill. If it comes from the City of Vero Beach, this change applies to your home through Nov. 20, with a mixed week after Nov. 21.
2. Taste bothering you? Fill a pitcher and keep it open in the refrigerator for a few hours before you drink it.
3. Keep fish or a backyard pond? Test before adding tap water, and use a water conditioner whose label covers both chlorine and chloramines.
4. Do dialysis at home? Call your dialysis provider or equipment supplier this week and tell them about the Nov. 1–20 switch.
5. Have a question about your water? Call the City of Vero Beach Water and Sewer Department at 772-978-5220.
6. Put a reminder on your phone for Nov. 21. That is when the city goes back to its normal method, and when anyone who changed a routine for fish or dialysis should check again.

For most of us, this is a three-week blip and a pitcher in the fridge. For the neighbor with a fish tank or a home dialysis machine, it is worth a quick heads-up. Pass it along.
