Yes, you should super chlorinate your pool to help prevent algae growth and ensure the water remains clean and clear while closed. We recommend super chlorinating your pool a few days before closing it to give the chemicals time to circulate and mix with the water.
Super chlorination and shock are often confused as they’re very similar. While both increase the amount of free chlorine in your pool, they are technically different.
When you shock your pool, the chlorine level is raised very quickly to a high level strong enough to kill harmful bacteria and other microorganisms. This high level of chlorine is called breakpoint chlorination.
On the other hand, super chlorination involves adding a large amount of chlorine to your pool in a short time. This process raises the chlorine level high enough to kill contaminants in your pool water but doesn’t reach the level of breakpoint chlorination.
