Nice.
I havent emailed this company yet but snow joe confirmed their red label flakes are 100% pure calcium chloride with no added impurities.
This safestep is the only thing i have that doesnt mix 100% clear and needs to be decanted after 24h which i dont like....
I may have mis-spoke.I would just caution that 100% calcium chloride only means they do not add any other ingredients, not that the product is free of impurities that might really be substantial.
I gotcha.Just don't misunderstand my point. Calcium chloride always has many impurities in it. The question is just one of how much of what.
I gotcha.
I would assume they just dont divulge the other 5-6%?
I guess were just hoping its water?
I just saw an add for dowflake, listed as minimum 99% pure. But the bag clearly says 83 to 87% pure....
What to believe.......hmmmm
Gotcha.Most calcium chloride is the dihydrate, which is about 77% calcium chloride and the remainder water, plus lots of other impurities. Some of these other impurities are present at large percentages, but are not a problem. Like potassium.
i analyzed several products long ago:

GREAT POINT!!!! Thanks for this. I shall do so!Great, let us know what you find.
Be a little cautious interpreting the results if you send it to a hobby ICP company as they have optimized the process for seawater, which this is now very different.
I'd recommend making it to about 70 g/L, since that will be close to the 35 ppt of seawater.
