Goner Goni? Can I save it?

[GuppyHJD]

I got a goni frag from a fellow reefer. It was headed to the trash bin and I offered to try and save it.
I thought it was covered in gha but I am not sure. I tried brushing it off and am not making progress.
I am wondering if a dip in hygrogen peroxide would help? And how to get it back to life? Extra magnessium?
Suggestions?
