While rainwater itself isn't inherently harmful to your pool, it can affect water chemistry. Rainwater may dilute chlorine levels and change the pH balance, leading to potential algae growth or cloudy water. To maintain a healthy pool, test the water after heavy rainfall and adjust chemical levels as needed. A well-maintained pool cover can also help prevent rainwater from entering the pool.
