I had a thought.

Suppose you want to run a SWG and salt is recommended at 3000 ppm (made this up for examples sake). You add the required amount of salt and test the water to make sure you hit the PPM needed.

Fire the unit up, and salt is converted to chlorine and returned to the pool. It eventually breaks back down to salt, and the process starts all over again.

With the FC of say 5 ppm, if you tested the pools salt content after SWG was operational, what would the PPM of the salt be? I assume once converted to chlorine, the "chlorinized" salt wouldn't register as salt?

If this is the case, we should be able to come up with a salt PPM recommendation that gets the good water feel without SWG.
