Evaporation in Florida's heat concentrates minerals at the waterline, where they deposit on tile.
What you might notice
- White or gray crust at the waterline
- Rough tile surface
- Buildup on water features

Possible causes
Appearance alone doesn't identify the cause. These are the usual possibilities a pro checks:
