The Science Behind the Salt

Salt is added to pool water in conjunction with the installation of a salt chlorine generator. The generator is comprised of a power supply which is wired at the pool equipment pad and a salt cell which is plumbed inline with the pipe returning water to the pool. Inside the salt cell are coated metal blades which receive a low voltage current. As salt water passes through, electrolysis occurs, splitting the salt and water into hydrogen and hypochlorous acid. This acid replaces the chlorine tablets or granules traditionally used to sanitize pools.


This process repeats indefinitely as the salt converts to acid and then the acid converts back to salt. Salt does not evaporate. Therefore, once the proper ppm of salt is reached, only small amounts of salt are required to adjust levels. Some things that affect salt levels are heavy rain, which dilutes the concentration of salt, or heavy pool usage (think pool party), when a significant amount of water might be splashed out of the pool.
 
Good morning, OF.

I've never had a manicure or pedicure though I don't think that is unusual for men ;)

Princess gifted me a manicure one time as a birthday present - I am 'hangnail phobic'. The one time experience was more than enough. :lau and it didn't really help with the hangnails.
 
I did find this:
"Your salt cell must also be inspected from time to time, about once every 3-6 months. If there is excess calcium build-up on the blades, clean it with Salinity Cell Cleaner."

So there can be some "free" calcium to be dealt with. But it seems more than likely that the chlorine kills off bacteria but probably recombines with the sodium since free chlorine is unstable so it looks for a friend ;)
 
While we do check our cell, when the salt levels are kept in the proper range, and not too high, pH is kept within the correct range, etc., we don't have to clean the cell often at all (maybe once a year). The small amount of "free" calcium is usually not a problem for the pool itself. Yes, there can be an exception, but it's not the average situation. In fact, depending on where you live, and the hardness of your rain water, sometimes in rainy season, it may become necessary to add a bit of calcium.

If you are getting hangnails, your skin is too dry. I like the lotion for dry feet to use on my hands and feet.
