I did not participate in that particular meeting but I think it is safe to assume it is magnesium chloride. Magnesium Sulfate is actually know as epsom salt and it is common practice to mix the two together (3 cups of Magnesium sulfate and 5 cups of magnesium chloride to one gallon of R/O water) to make a balance magnesium supplement. Hope this helps, Jim

Yes, should be magnesium chloride. They are NOT the same.
