I don't grow hydro, but this is good info. I come in here and absorb knowledge from you guys sometimes. I actually have that shit that I used for my hot tub occasionally. But since my water has Ca already bleach was a better option for my spa. I also used muriatic acid to lower the pH, but that probably wouldn't go well if you fed that to a plant, lol.Probably calcium chloride, calcium carbonate and calcium hydroxide left from manufacturing. Mine is about 60-70% pure. Best of luck!
