Pool foam after adding shock can be due to high organic matter (like sweat, oils) reacting with the shock or an imbalance in pool chemicals, especially with algaecides that are surfactant-based. To resolve, test your pool's chemical balance and adjust as necessary. Consider using a pool clarifier to help remove the foam. Regularly cleaning and maintaining your pool's chemical balance can prevent future foaming.

FAQs & Answers
