How often does the water in cruise ship salt water pools exchange? I know that they are continually pumped and exchanged with the ocean (except when close to shore), but at what rate? How many times per day is the water changed? If you don't know, could you refer me to someone else? I would very much appreciate it.
Some pools are fresh water, where the ship has their own water filtration system. If you are cruising on Princess, they do NOT have salt water pools and the same for some Royal Caribbean pools, the newer Freedom class are also not salt water.
As for how often the others change the water, I really have no idea.
