What do you think is the best product to make saltwater and why? I have used at least a half dozen different brands over the years, probably IO for 15 years simply because of cost, availability, and proven consistency. I am ready for a change if there is something better out there that has added value for the added $s or even something comparably priced. An additional $40 a bucket to get $1.14 worth of "extra" Ca, ALK and Mg is not really what I am looking for, I can add simple ingredients like those easy enough. So, what other reasons do you prefer the salt you use?
