carbonic acid
Water make up.
Improper chemical service.
Redwood hot tub: bad chemical maint.
Fiberglass spa: same as above.
Plaster spa: It will also be the lime in the plaster mix. This spa will always have a demand for acid to adjust the pH and total alkalinity. And include all of the above.
Do you mean a redwood hot tub? Or a fiberglass or plaster spa?
Use baking soda or muriatic acid in small amounts and test the water within 10 to 15 min. and adjust again if needed. It will not take much to change the chemical balance of the water.
In many cases, foaming in hot tubs is caused by soap residual on bathing suits-
better to wash suits by hand and rinse thouroughly, or not use them at all!
Additionally, foaming can occur when lotions, oils, or cosmetics enter the hot tub- try to keep them out! Most important is a clean filter and properly balanced hot tub water-- see a spa care professional for testing as needed.

Sodium as a byproduct from the electrolysis process used to make the chlorine (Salt is sodium chloride)
carbonic acid
Yes.
Not at all.
Either the to much salt was added or the sensor is out of calibration or bad.
Sorry, but swimming in a saltwater pool is a lot different than swimming in the ocean. In the ocean, pollutants like oil, gasoline, and trash combine with fish urine and dead animals. Another big difference in a pool is that there are no waves! In the ocean, rip tides and tidal waves are a big part of the ocean's cycle. In your pool, waves are non-existent.
sodium chloride
Yes, you can add a clear saltwater system to a ProSeries 14' X 42" Metal Frame Swimming Pool.
In a typical saltwater swimming pool nothing living other then micro organisms should be able to survive. In a saltwater pool with water, filtration and components designed for marine life, they could.
Obviously the pool floor is not smooth.
No, salt does not damage the plaster. Improper water balance will.
yes running the filter while swimming helps the filtration process. Also if the pool is saltwater then the system will replace chlorine being used while bathing.
Adjust your chlorine generator levels.
A fresh water swimming pool is a swimming pool that does not use a saltwater chlorinator. A pool that used a salt water chlorinator has salt added to it to so that a salt water chlorinator can electronically convert part of the salt into chlorine. A fresh water pool has chlorine added to it directly either manually or Automatically.
