KZ Immuno-Stabil ?

[mws]

I used it once. Buy next day I lost xenia and lawnmower blenny. Every one else was gasping for air. Devils' hand went into shedding mood. I don't know if the
ISF is to blame, but never will use it again. I only add one drop.
Could not find any info if it's reef safe.

So if anyone like a full bottle(100 ml) for $20, let me know.
