After researching past threads, I settled on buying 40lb bags of Diamond Crystal 40-lbs Salt Pellets. Here's the link to the product on the Lowes website:
Right on the website, it says 99.8% pure and I was expecting it to say this on the bag too......but it doesn't and now I'm second guessing myself. And now I'm reading a different thread on here that says I probably bought the wrong stuff. Should have gotten solar salt I guess? Can someone confirm before I start dumping them in and potentially mess everything up? Thanks.
