Hello Wesley and Massimo. I was not able to get much information about this element and its possible impact to corals. I also have asked Korallenzucht because of CoralSnow Plus and they have confirmed me that they use the product since a longer period regular on their own systems without having any problems.

Here you can find a analysis of the zeovit material from a reefer, it is a couple of years old but it indicates that the material does not contain this element:

I have observed TN starting from the tips just in the case while the PO4 level was decreased to quick, also the additional usage of PO4 absorbers to the system can cause it so this might be some kind of link to CoralSnow Plus which does decrease the PO4 level.
