Chemipure gets my skimmer crazy

[Biotech]

Bought some Chemipure this morning and put 2 bags into a PhosBan reactor. Within an hr, my Euroreef CS8-2 went nuts with diluted wet foam. This is my first time using Chemipure. I used to use Kent Reef Carbon and it never did it to me. Anyone with the same experience like this?
I have turned off my skimmer and plan to turn it back on after a couple of hours - hope it will work. Welcome any suggestion.
