I don't think the salt has anything to do with your (or their) problem, so don't go spend the $ on it if you don't want to. You can test your source water with the same kits if you want, or see if you can come by a tds meter.
I've never used distilled water, but I'm sure others have. It might be worth looking into as an option.
