Hello i was wondering if it is safe for my expobar to use hard water with the ion exchange softener that came with it. i tested the water before the softener and it is about 200-250 ppm. i tested after running it through the ion exchange it the water was about 30-50 ppm. If someone could please help me with this i would be very appreciative.

Yes, I believe that it is safe if I remember correctly.  But, it has to be maintained regularly, depending the water used, and time.  If it can be well maintained, it will be safe.

But, this water can be used for coffee, black tea and others only, not good for Chinese green tea, because it brings bad taste to green tea, and some components of it may damage the green tea.  For us, we use filtered softener, not ion-exchange type.
