Hey Steve
I have used Joe's about a half dozen times, in the last 3 weeks. The treatment leaves a white flocculent residue that disappears within the hour. My mushrooms don't seem to react to it at all, the Zenia's looked ****ed for about a half hour as does the zoo if it curls in some white stuff.
Makes a bit of a mess but doesn't seem to hurt anything but aphasia(almost instantly,if they ingest it).I gravel/rock vacumn after and roll in a small water change.
Sorry,if you were looking for volunteer control for mushrooms and zenia hey just laugh at it.
