We have a Culligan system we bought last year. I let the salt get down to about nothing (I know that's bad, spring is SO busy around here) and when I filled it almost 2 weeks ago it still isn't softening. I can always tell cuz the dishes are spotty, filmy and rust stained after running them in the dishwasher, esp. the silverware. Anyway, I did do two regenation cycles, one after I filled with salt, the other couple days ago. Anything else I should look to do? Thanks!!!
