Got lots of suggestions PMed to me... here's one that is working quick: boiling water!
I filled a stainless 5 gal pot with freshly mised salt water and brought it to a boil.
I connected a small pump to a hose with a ball valve for flow control.
I set the pot on a board next to the tank, dropped the pump in and turned it on. I set the flow very low, would fill a 8oz cup in 4 seconds, and placed the hose directly over a cluster of these devil anenomies.
After 1-2 seconds, the evil little thing would shrivel. Move to the next and next..... Took maybe 5 minutes total to hit half the tank and drain the whole pot.
30 min later, the tank temp is only up 5F over when I started and the little devils are falling off the glass and rocks where I sprayed bioling water. Other soft corals only an inch away are fine.
Boiling salt water. Just make sure you use a stout hose, the vinyl ones soften fast!
Thank you all for your help!
