Hi,
No to Dolomite...okay. Well, it is a higher risk solution, since dolomite grade do vary. IMHO, the best dolomite would be as good or better than the current Caribsea stuff. I guess you are trying to save money. The best midway point is to use silica sand. It can be found in white, and it will not dissolve in to the water (very easily).
As for dolomite dissolving...we will have to argue about this at the meeting. Anyway, here's some interesting info on magnesium :
