Hello!
Yes, E-Z Pool All-In-One works very well with fiberglass pools.
Why it’s a good choice:- Helps prevent staining and scale
- Keeps water clear and balanced
- Gentle on fiberglass surfaces
It contains a small amount of copper for algae control, so just keep your water chemistry balanced to avoid any potential staining.
I hope this helps!
