Yes, I've read and discussed their marketing propaganda before.
Organic Salt mixes
I don't have any idea what that actually means. At the least it is quite ridiculous convolution of a scientific term for something that is nearly if not entirely inorganic. They are actually criticizing other companies for adding organic compounds.
That write up is, unfortunately, quite misleading. EDTA and metal chelators are not used in typical mixes like Instant Ocean.
