I use econuts and I have soft water. Seems to do the trick. It's also good for sensitive skin! The only issue with them is that they go in a little bag that you pop into the washer but you need to take it out before the extra rinse so it's kind of a pain to dig around looking for the little bag.
I also just saw a sale on detergent at littlelovebuns.com- go to detergent and you'll see the one!
