It's a Culligan which we have had for 15 years, I'd added 20 kilos (about 40 lbs) of salt, but the water was still hard so I added another 20K bag to the drum. I assumed it was that, because when I examined the potting soil with a magnifying glass, I could see salt crystals on the surface! It was odd though because I've always used softened water for my seedlings and had never had a problem before then.
