What is the acceptable level of bromine for a swimming pool?

The acceptable level of bromine for a swimming pool is generally around 3 to 5 parts per million (ppm). This range is effective for maintaining sanitation, as bromine works as a disinfectant by killing pathogens and controlling algae, ensuring the water is safe for swimmers.

While some sources may indicate a minimum acceptable level of 1 ppm, that amount is typically considered insufficient for effective sanitization in a recreational swimming pool environment. On the other hand, levels above 5 ppm, such as 8 ppm, can lead to discomfort for swimmers, including irritation to the eyes and skin, and may also produce a strong chemical odor, which can deter usage.

Overall, maintaining bromine at approximately 3 to 5 ppm strikes a balance between effective sanitation and swimmer comfort, supporting a clean and safe swimming experience.
