CRUISING71 Posted September 22, 2009 #1 Share Posted September 22, 2009 Hello, My daughter asked me this question and I don't know the answer to her questions. Can you help? She wants to know why all the pools on the ship are salt water? Are the water coming directly from the ocean? Thank you, Link to comment Share on other sites More sharing options...

She wants to know why all the pools on the ship are salt water? Are the water coming directly from the ocean? Thank you, Let her know that the pools are emptied every night -- refilled every morning -- so that reduces chemicals that they don't want to end up in the ocean --- and that modern ships actually produce their own fresh water using a desalination process -- very expensive and time consuming -- filling the pools with that water would be rather wasteful.

ChampionCruiser Posted September 22, 2009 #5 Share Posted September 22, 2009 Not all ships use saltwater, though. Princess' pools are freshwater, which was AMAZING:rolleyes: But I guess saltwater might be more practical... Link to comment Share on other sites More sharing options...

OrdieJ Posted September 22, 2009 #7 Share Posted September 22, 2009 Let her know that the pools are emptied every night -- refilled every morning -- so that reduces chemicals that they don't want to end up in the ocean --- If they are emptied every and refilled every day, doesnt that create more chemicals being released in the ocean? And Royal Caribbean's Freedom class ships use fresh water in thier pools. Link to comment Share on other sites More sharing options...
rottiemom Posted September 22, 2009 #8 Share Posted September 22, 2009 But it is filtered & treated with chemicals. I did not know that they used chemicals after being so happy to hear that the pools used saltwater. I am disappointed to hear that. Link to comment Share on other sites More sharing options...
sprockie Posted September 22, 2009 #9 Share Posted September 22, 2009 I have to say I am thrilled to hear they are emptied often. One thing that makes me cringe is how much pee is in those pools!!!! Link to comment Share on other sites More sharing options...
CalmCruiserNC Posted September 22, 2009 #10 Share Posted September 22, 2009 From what I understand, the salt water is filtered but not chemically treated, so no chemicals are being released into the sea. Link to comment Share on other sites More sharing options...
yst347 Posted September 22, 2009 #11 Share Posted September 22, 2009 Salt water does not require any additional chemical treatment. Many home swimming pools use salt instead of chlorine today. Link to comment Share on other sites More sharing options...
CapeCodCruiser Posted September 22, 2009 #12 Share Posted September 22, 2009 Funny what a little google will do: http://shop.solardirect.com/product_info.php?products_id=290 The Pool Pilot is so rugged and effective it was chosen exclusively • to serve as Carnival Cruise Line's onboard pool purifier system! • Designed to operate under the most demanding 24/7 high-volume • use, the Pool Pilot units easily stand up to use with pure sea water! WATER QUALITY A Pool Pilot system will eliminate the discomfort and inconvenience of harsh chemical reactions like red eyes, green hair, irritated skin or faded swimwear. Pool water will retain constant low-levels of ph-balanced chlorine that purifies the water while making it soft and silky to the touch. Link to comment Share on other sites More sharing options...
astropilot Posted September 22, 2009 #13 Share Posted September 22, 2009 I did not know that they used chemicals after being so happy to hear that the pools used saltwater. I am disappointed to hear that. Ditto. I don't think they are treated. They are emptied and cleaned every night though. Link to comment Share on other sites More sharing options...
gill_boo Posted September 22, 2009 #14 Share Posted September 22, 2009 I think Princess is the only one who uses freshwater. RCL is salt water as well. Link to comment Share on other sites More sharing options...
wxtrix Posted September 22, 2009 #15 Share Posted September 22, 2009 HAL uses freshwater too, and I'm pretty sure that NCL did too on our cruise with them. Link to comment Share on other sites More sharing options...
Max Circus Posted September 22, 2009 #16 Share Posted September 22, 2009 Many home swimming pools use salt instead of chlorine today. That is true. Although the systems I am familiar with use the salt to produce chlorine via chemical reaction. And these home salt pools are closer in saline content to contact lens solution - pretty mild. On a ship, it will vary since salt content is different around the world. Link to comment Share on other sites More sharing options...

frayedend Posted September 22, 2009 #18 Share Posted September 22, 2009 Would it be safe to assume there are fresh water showers next to the pools to rinse off. I don't mind swimming in salt water, it's the residue after that bothers me. If I can rinse off quickly, no problem. Link to comment Share on other sites More sharing options...
yst347 Posted September 22, 2009 #19 Share Posted September 22, 2009 The systems don't "produce" chlorine as the chlorine is already present in the salt. The system ionizes some of the chlorine in the salt making it available to sanitize the pool. Link to comment Share on other sites More sharing options...

Chemistry wasn't my favorite subject. Salt is NaCl (Sodium Chloride) - so if you take out the salt (Na), all you are left with is the Chloride (Cl). Now if I had only remembered that for my 10th grade final exam. :) Link to comment Share on other sites More sharing options...

That and the instructions on our salt water chlorinator clearly states........if my salt level is too low the unit will not produce chlorine:p Link to comment Share on other sites More sharing options...

Thank you for the science lesson - I knew it was something like that but wasn't exactly sure how it worked. I just know that with this type of system the water is not really strong with chlorine:) which works best for me as I am very sensitive to chlorine odors.

zqvol Posted September 22, 2009 #24 Share Posted September 22, 2009 Hello, My daughter asked me this question and I don't know the answer to her questions. Can you help? She wants to know why all the pools on the ship are salt water? Are the water coming directly from the ocean? Thank you, The water is sea water, pumped directly from the ocean. It is neither filtered, not treated with any chemicals. It is replaced on a constant basis, and is really fun to swim in. In the event any accidents occur (including glass being broken) the pools are drained and refilled in a short time. There is no need to filter the water because the ocean where it is pumped from is very clean with no debris or salt. Pools are sometimes refilled at night but not every night.
