Hard water/detergent help! Eco Sprouts?

[njuhan]

Ok so we have extremely hard water. When we lived in the states I used tide without any problems. As soon as we moved here to germany we started having issues. I tried adding calgon to my tide, didn't help. Switched to specific cd detergents, made things worse. Tried a few other detergents, tried homemade...just about everything. We have terrible ammonia problems, nothing seems to be getting the diapers really clean. I have seen a lot of positive reviews about EcoSprouts working great with hard water so I ordered some last week. Do I need to use calgon with this detergent? Does anyone have any reviews on this detergent? Any advice??
