Can I perform shock treatment (chlorine-shock or high-dose salt treatment) while my pool is covered with Coverseal?

Because the membrane significantly reduces algae growth and prevents debris from entering the pool, shock treatments are rarely necessary.

However, in certain situations, a shock treatment may be required. In that case, it is strongly recommanded to leave the Coverseal fully open for 24 to 48 hours to prevent high chemical concentrations from building up beneath the cover, which could potentially damage the membrane.
