Hard Water vs Soft Water Explained: What's the Difference?
Water containing 0 to 17 parts per million of hardness minerals is considered soft. Water with 17 to 60 parts per million of hardness minerals is mildly hard. If water has 60 to 120 parts per million of hardness minerals, it's moderately hard. Between 120 to 180 parts per million of hardness minerals gives water a 'hard' status.
