Gotcha. The "pool guy" explained this to me and I must have misunderstood. 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.

LOL! That and the instructions on our salt water chlorinator clearly states........if my salt level is too low the unit will not produce chlorine

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.

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.

Funny how some people post (esp with some "authority")with reading the entire thread!

Salt water pools use Bromine, not chlorine.

Some of RCCL has fresh water pools on the Freedom class ships.

I prefer sea water anyway, just for the waves.

I think Princess is the only one who uses freshwater. RCL is salt water as well.
The pools on the RC Freedom Class ships are also fresh water.
