Would either of these snow melt products work/be safe for pools?

I have someone up in NJ right now who can pick up some of these for me if they are worth it.

Pool store sells 50lb labs for $50, so these would be much cheaper if they would work the same based on volume needed to add to my pool in the summer. I could get a couple of these and have them driven back next month to use if it would be the same.

Ice melt products are far from pure. They're the lowest grade you can get. They are full of contaminants like bits of rock, metals, etc.

I used a 50lb. bag of Snow Joe ice melt from Amazon, which I gradually mixed in a bucket to dissolve before introducing it to the pool. It was a tiny bit dirty, but no solid chunks of anything. You could see a little hint of tan in the bucket but once it hit the pool the color and cloudiness was gone. They claim 94% pure calcium chloride, so I have some mystery contaminants but it doesn't seem to have caused me any headache.
