Tunze reef salt, anyone use this???

[Captain Nemo]

So I am looking into this salt which says it is a "complete salt" and you are not supposed to have to add trace elements. Anyone use this or know anything about it?

I use Tunze salt now for a couple years and really like. It is a more "moderate" salt mix with no extreme levels of something.
It dissolves within a couple minutes and no residue after mixing like some other mixes.
I usually get the box with 4 bags and throw only one at a time in a bucket.

I am totally contemplating it, but not sure if I want to use it or not. I am happy with the seachem I am using, but thought I might try this.,
