When should Pool Clarifiers be Used? Pool Clarifiers are not meant to be used all season long, but are quite helpful at pool opening, after an algae bloom, or battles with cloudy pool water. Follow label directions, but most pools can be retreated after 5-7 days, with a lower dosage than initially used.

How long after putting shock in pool can I add clarifier?

Some clarifiers are polymer based and the shock can act to break up the polymer causing the clarifier to be ineffective. It's best to shock your pool before and wait a day or two before adding clarifier.

How long does it take for pool clarifier to work?

If your pool is just mildly cloudy and you are not in a rush to clean it out, a clarifier may be your best bet. A clarifier requires less work and less water but can take to two to three days to achieve the results you are looking for.
