Post-Storm Checklist

After a storm, test and clean before you treat. Leaves and soil consume chlorine and clog filtration.

  • Empty skimmer and pump baskets
  • Brush walls and steps to knock off debris film
  • Test pH and free chlorine and correct gradually

The One Thing People Miss

Run the filter longer for 24 hours after big debris events. Chemistry alone cannot fix a filter that is not capturing the fine stuff.
