Common Mistakes to Avoid
|
Forgetting to Drain Equipment
Water freezes and cracks pumps, filters, and heaters.
Fix: Remove all drain plugs and blow out lines.
|
Unsecured Winter Cover
Loose covers let in debris and sunlight, feeding algae.
Fix: Use cable winch or cover seal. Add air pillow.
|
Skipping Algaecide
Cold water still grows algae without treatment.
Fix: Use a complete winterizing kit with algaecide.
|
Closing Too Early
Algae stays active above 60 degrees F under the cover.
Fix: Wait for consistent water temp below 60 degrees.
|
