There is no dump question.
You need both to make the 3rd part in Randy's recipe. Randy explains it very well in this article:

FYI, there is a sponsor here, caco3reef, that sells all chemicals you need for Randy's recipe. After all the saving in shipping and duties and such, caco3reef's price is similar to BRS's price.
If you want to save more, you can buy baking soda and bake it...but yeah...caco3reef has it all.
