How much Clorox?

36-48 hours before you plan on closing the pool add the algicide (polyquat is what is recommended) to the water and bring your pool up to shock level using the pool calculator to determine the amount of chlorine you need to add depending on your CYA levels. Allow the chlorine level to drop to half of the shock level and button it up.
