maybe from the Pacific then. Those are the only two species I know of personally, but that doesn't mean much. So much diversity in macros. I think it would be a good idea to have a thread of "Who has tried magnesium on byropsis without results", and try to see if there is differences in the species, or to see if there is some other parameter that is also important etc....
