Yes, sunlight does reduce chlorine levels in pool water. UV rays from the sun break down chlorine molecules, decreasing the concentration of active chlorine that sanitizes the water. To manage this, it's recommended to regularly test your pool's chlorine levels and adjust as necessary, especially during peak sunny hours or when the pool is used frequently.
