What do you think of the idea of adding salt to a hot tub. I do not mean a salt water clorine generator. I would still use dicholr. But adding salt to bring it up to about 1000 or 2000 ppm. This would be to make the water softer and silky, to make it feel better. I know people raise the issue of corrosion, but I have a salt water swimming pool, at 3000 ppm, and this does not corrode the pool heater or other pool parts. Why would a lower level in a hot tub corrode hot tub parts? Also, what about people who add a SWG to their hot tub? Do they experience corrosion?
