Anyone using water softened tapwater in their reef?

Well there is the following link that says no:

But from what I have read about people's experiences, they have found no problems with using water softeners, but most use them before a RO filter anyways. It will actually be a benefit to your RO membranes and you will have no problems with your top off. Not sure about your tap water for the initial setup.
