pool salt in salt water rock?

i went to home depo to day and got some diamond crystal pool salt because i can not find rock salt anywhere in this LITTLE one tooth town.can i use it.

Bag says -Natural- High purity-Additive free- Disssolves quickly.99.3-99.9% Pure

can i use it to make rock??????????????????????????????????

 

bump

can anyone who does not have a specific answer to this question refrain from posting please

unless it is to bump the thread for the attention of someone who does know if pool salt will or will not leave any harmfull residue after it dissolves during rock making

thanks everyone

Dusty- I dont know as I have never used it, I have googled it for you but cant find anything helpful
