clorox calcium pool and spa calcium hardness increaser

[scrapdaddy]

Ok so I have been on a fruitless search for dowflake found a thread stating one could use prestone driveway heat to which I do not have access to living in South Carolina. After completing a web search for calcium chloride I was directed to clorox pool and spa calcium hardness increaser which would be available at my local lowes. Not being completely comfortable with my knowledge of exactly what was in it I called the company to get access to the MSDS which would list all ingredients. To my delight it was 100% calcium chloride. So my question is would any issues arise from this brand or the type of calcium chloride it may be. ( this is for the two part recipe # 1 ) Thanks in advance for your input!!!

It may be fine, but one cannot know the purity from an MSDS alone. How much copper, etc.

Thanks for your time!!!

Any suggestions for a more desire-able/trusted food grade substitute for dowflake??

Some folks use Leslie's Pool calcium additive without apparent issue.

Hmmm I was thinking... I know scares me too!! If I mixed a batch up using distilled water and then tested for TDS that should show any copper. Is this correct or would it not be detectable?
