I use calcium chloride from Dr Forster and Smith, which certified and also used in their Liveaquaria facilities.

As for baking soda, Randy had stated clearly years ago that you needed to use food grade that sold in supermarkets.
One more note for other supplements, you need to use USP grade that is acceptable for food, drug, or medicinal use.

I got my calcium chloride in a sealed container as well from Amazon. Aside from closing the cover tightly, I also rubber band the bag that contains the calcium chloride squeezing out all the air before I tie it

Yes it is.
By the way, I will suggest using baking soda as it is (Randy's #2) instead of baking it to turn it into carbonate.
Coral consume baking soda directly.

It is the "Drive Way Heat" product that I will not use regardless what container it came in.
Also it contains up to 1% of Bromide.
There is no much know about what excess bromide can do in reef aquarium, but when Dow Chemical changed their DowFlake manufacture process and let bromide in it, there was a lot of concern in the hobby.

As a side note (dong mentioned above) baking soda does not require the baking step. The baking releases extra CO2 and turns it into sodium carbonate (as opposed to sodium bicarbonate)
Baking soda (NaHCO3) sodium bicarbonate...will have a none to slightly lowering effect on ph for a few hrs on tank when added at once.
Soda ash (Na2Co3) sodium carbonate... will have a significant raising effect on ph and will last for maybe an hour when add at once.

Both can be dry measured and dissolved into a bit of ro water and added to the tank if one prefers.
