Just my opinion (again LOL!) but I just don't see the Salinity being any better than any other quality salt. Sure - they have targets and acceptable ranges for each batch, but I have to believe that's true of any good salt manufacturer. I think it's all just marketing hype to get folks to believe it's the best, and to pay more money for something no better than many other salts. It sounds just like things my company used to do. The worst results and cloudiest SW that I've used was their Reef Salt. Anyway - you know me Glenn - I have my opinions!
