Query: Not dissolving in our well water

This product is just not working for us. We use our own well water which gives us no problems with anything else, but this product is not dissolving and we are left with lots of white specks on most of the dishes.To test, we ran a load of dishes through twice with this produce and still had the white bits after the 2nd load. Then, without changing the load or cleaning anything, we popped one of those cascade tablets into it for the 3rd load. Everything came out clean and looking good.
