Heavy rainfall fills your pool with substantial rainwater. In case you experience acidic rain, the water in your pool shall mix with rainwater which shall lower your water pH levels. It is advisable that pool water be maintained at a pH level of slightly lower or higher than 7.2. Acid rain can have its water at a pH of as low as 5.0. This shall in turn lower the pH value of your pool water.

Now that we expect dilution of the chemicals in your pool. Check for the amount of chlorine in your pool and the pH level. If there is an imbalance, then consider adding some chlorine and balancing the pH of your pool water as required. Clear any mess caused by rain around your poll and get ready to dive into that water again.
