    which salt should I use?

    I am going to go ahead and get my salt added to my pool. So last night I went to my local "DIY BOX STORE" and they had an entire shelf full of various salts for softeners and such. some pellet, some coarse, nothing fine, like actual pool salt comes as.

    anyway, I narrowed it down to 2...one is the cargill 99.9% pure solar salt in the blue 50 pound bags..they are $5.89 a piece. OR.....they have this white bag, not sure who makes it..but it said coarse rock salt - 98.9% pure..this comes in 80 pound bags for $7.00 a bag.

    What should I go with? the larger bag, or the smaller, higher purity salt?

    Thanks for any info.

    I use the cheapest 99.9% pure 'solar' salt that I can find - pellets or coarse - they both dissolve just fine. Don't buy anything with additives for rust, etc.

    yea...I know about the rust inhibitor, and won't use that..but just wondering what difference there is between 98.9% and 99.9% purity.

    It is generally not suggested that you purchase anything less than 99.4% salt for use in your pool. It is a quality control issue more or less. This is because there is really no way of knowing what that other 1% may be and it could be something that you may not want in your pool such as metals or other contaminants.
