Aquaforest was still extremely low in S and it's most definitely not testing error. Both their Reef and Sea branded salts were low. Only salts I would not use at this point besides those with organics would be the Aquaforest Reef and Sea salts due to that.
There are many other oddities but I have a much better understanding now between getting all these back, my testing, and talking with Carl from ENC Labs. When I have a chance I will recap this.
But overall I feel the list is showing a good average of what one can expect to see in a salt brand and useful to compare.
