It's possibly scale but it would look like a deposit or a flake and not a fine chalk , so you can toss out that first answer. It's likely the gel coat breaking down. Scrubbing it only, as I've seen suggested will be only a temporary fix.
Boat hulls get this all the time. You can use a marine grade fibreglass cleaner. They're all bidegradable these days and will require little elbow grease. Just remember to rinse.

It is hard water build up. You will have to drain it and clean it with vinegar and a scrub brush. Rinse it well and refill it.
