Yes, to some degree I am sure you might be getting things (desirable or not) in there that arent in sw mixes.
That being said there is one kind of salt mix that claims to exactly duplicate the EE's of the ocean...I think its the seachem brand. I kinda want to try it, its an expensive bucket, but its apparently 225g of mix rather than your standard 160g.
