You will need a pool clarifier chemical when your swimming pool water becomes:
- Not cleared by 12-24 hours of filtration.
If all the chemical levels are properly balanced, cloudy pool water can be caused by fine debris suspended in the swimming pool water. Dust or debris particles can be too small for the pool filter to remove from the swimming pool water, and may pass directly through the pool filter. A pool clarifier chemical will group together very fine particles of debris into larger bunches, which can be more easily trapped by the pool filter.
