The ideal chlorine level for a pool is generally recommended to be between 1-3 parts per million (ppm). This level ensures effective disinfection of the water, preventing the growth of algae and bacteria, while also being safe for swimmers. However, it is important to note that specific recommendations may vary depending on the pool type, climate, and other factors, so it is best to consult local health department guidelines or a pool professional for the most accurate information for your specific situation.
