Adding water will indeed lower chlorine levels in a pool or spa. When you dilute the water, you are essentially reducing the concentration of chlorine along with other chemicals. However, it's important to maintain the proper balance; too much dilution can significantly reduce the effectiveness of the chlorine in keeping the water sanitized. After adding water, always test and adjust the pool's chemical levels to ensure they remain within the recommended ranges for safe and enjoyable swimming.
