I guess the reason I find that hard to believe is that every pool with an SWG is operating at or above the "limit" of 3000 ppm. Most SWGs recommend something in the neighborhood of 3000 ppm of salt alone and some are designed to work at 6000 ppm and even higher. I've yet to hear from anyone with an SWG who didnt rave about it.
