It is my undersaanding that F&S calcium chloride is anhydrous. Accordingly, if you're using Randy Holmes Farley recipe for two part, you will need two cups of this made up to one gallon of RO/DI water. Hope this helps.
I did ask DFS about their calcium and they responded it was anhydrous, so redfishbluefish is correct.
Remember, it gets pretty hot when mixing anhydrous calcium chloride! If you just let it sit and not mix well you can melt your containers.

Yes, they also do claim online (indirectly via the heat comment) that it is anhydrous.
