I heard this too, is it the same on the Grandeur? Do all cruises do this? I "heard" that they fill the pools by pumping in ocean water, an its not done until you leave the dock?? Doesn't seem like very clean water, and how is it maintained with all the bodies that are in and out of it??
The Navigator and Sovereign also have salt water. I think the water is cleaned somehow because it was clear on both ships.

All RCI ships have onboard water purification systems built into them....All of the water that is used onboard comes from the sea....the pool water is still salt water but it is cleaned and chlorinated...

I thought one of the main draws of visiting the Caribbean was the crystal clear water at the beaches. I think the only reason not to use ocean water in the pools is taste (and perhaps that's not a good reason to use fresh water, since it would be very hard for RCI to regulate drinking the pool water, and we know that beverages cost extra, right? <grin>)
With all the perfectly serviceable salt water around while at sea, I could not imagine any cruise line wasting fresh water to fill a swiming pool. It has to be more economical to fill the pools with saltwater, even a couple of times a week than to fill them with potable water, and then keep them clean enough for the bathing loads they support..
I was told that the RCI ships that have a separate pool for the kids is freshwater. All the cruises I've been on used salt water in the pools. Also, about half way into the cruise, the hot tubs are drained and cleaned. I'm not sure if these are salt water, but I would think the salt would be harsh on the hot tub plumbing/heating elements. I've been to some pools that use salt instead of chlorine to sanitize. It is much easier on the hair, skin, and bathing suits!
