Our dishwasher (very nice, we bought it new when we moved in 2008) doesn’t clean so well. I guess it is because of our hard water (i’m nearly convinced, but then sometimes I think we have soft water when washing my hands, the soap won’t come off).

How many grains do we need? 3 full baths, with 2 separate water heaters…
Sounds like 30000 is for 1-4 people (with our new baby, that makes 4, but with company, we can get up to 8 or so here at once).
