After reading posts on another board, I was wondering are the Pools on the Millenium, fresh water pools or salt water? Guess it really doesn't make that much difference other, than the salt water stains swimsuits. More rinsing! But, thought I would ask.
Will be sailing Millenium Sept 13 -23, western Caribbean.
The pools on the Millennium and all the Celebrity ships are salt water. We've sailed most of their ships and have frequented the pools and hot tubs many times without ever experiencing salt water stains on our bathing suits.
One caveat about chlorinated saltwater. Salt acts as a catalyst in the bleaching process. I tend to spend a couple hours each day in the regular pool or the thlassotherapy pool. The chlorinated saltwater can do a number on your bathing suit color. What once was a navy Blue Gottex swimsuit (and not cheap either) is now purple and royal blue!!!
So.....save your good suits for the beach or sunning... and bring the oldies, but goodies for the pools.
Actually, salts are neutral and do not react with anything (they are just annoying). The main thing in treated pool/spa water that causes bleaching is chlorine. Chlorine reacts strongly with anything in its path. There are other compounds that do this, but salts and saltwater are not included.
Chlorine is extremely toxic; once it reaches a level of about 10 ppm (parts per million), it is "Immediately Dangerous to Life and Health" according to the US National Organization for Safety of Life and Heath. No wonder it bleaches our suits!
Typically, public and cruise line pools, even those with freshwater with have a residual chlorine levels around 1 to 3 ppm; This is industry standard for pools.
The reason chlorine is used because it is the least expensive alternative to treating water. Any water that someone may consume (such as a pool), must be close to drinking water quality. Today, many techniques are used other than chlorine for drinking water, such as ozone (which many of us use in our spas) and UV light).
The bottom line is that it is not salt water that causes the itching and bleaching, it is the chlorine. The “freshwater” areas seem to be located in “adult only” areas so they have a lower chlorine (Cl2) residual.
