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. When clearing turbid water conditions, remember to keep your pool water balanced properly and run your pool filter nearly 24 hours daily.
Be careful not to overdose pool clarifiers, especially if you also use a metal sequestrant product in your pool. Too much clarifier in the pool can act as a dispersant instead of a coagulant, compounding your water problems!
The terms are sometimes used interchangeably in other industries, but for swimming pools and spas, a Flocculant will attract suspended particles to itself, resulting in marble sized clumps that sink slowly to the bottom of the pool. The filter pump remains off during treatment, and after 8-12 hours a thick white carpet needs to be slowly vacuumed – to waste.
Clarifiers on the other hand, work with your filter to trap visible and invisible particles floating in the water. Some particles may settle out, but most do not become heavy enough to sink. Instead they are drawn into the filter with constant circulation during treatment.
