Can I perform shock treatments (chlorine-shock /massive addition of salt) in the water of my pool protected by Coverseal?

The membrane that strongly limits photosynthesis and prevents leaves from falling into your pool should keep you from having to resort to shock treatments to purify your pool water. Nevertheless, under exceptional circumstances, this type of treatment may be considered. However, it is strongly recommended to keep the Coverseal open for 24 to 48 hours, to avoid any excessive concentration of chemicals that could damage the membrane.
