Out of those, the most likely sources, and I'm not say that they are very likely, would be the magnesium or alkalinity supplements. I might try dosing some baking soda for a while. Dosing the Reef Carbonate into some freshly-mixed water and testing for carbonate might be interesting, too, but I don't know how much to add to make a detectable difference. The description of Reef Carbonate says that it'll tend to raise the pH over time, which makes me think borate buffering, but there's not enough information to be sure.
