Stopping stn

[SteveConn]

I trim them back as much as possible then superglue a barrier between the dying spots and healthy tissue. I make a barrier as well where I cut with a liberal amount of superglue. Seems to work sometimes if I've caught it early on.

Yeah I've cut, glued, trimmed, and dipped. No hope yet.

Just don't want to loose all of his corals.
Funny though I picked up some stn acros a few weeks prior from lfs and all are good
