Can't get BTA to detach

[Aquavaj]

Neglected my biocube 29 a bit and got overrun with GHA and bubble algae. Have since moved the clownfish and banggai cardinal to a 40B started with live rock from my reefer 425 sump. I have 2 BTA (split from 1) still in the B29 that I'm trying to move over as well but can't get them to detach. I have placed a powerhead right in front of it for a day now and it's deflated but show no signs of letting go nor has moved an inch. I can try breaking the rock but that's the very, very last resort as I don't want to risk cross contamination or damaging the foot if the rock breaks between the foot. What else can I try?

I got mine off by holding the rock upside down water and gently (super gentle!) coaxing the foot off the rock. It took probably 5 or 10 minutes

Take rock out and hang rock over tank with nem just above the water line should detach and fall into the tank.

If you can slide a toothpick under the foot and twist the tooth pick the nem should detach really quickly they hate this. Be super careful not to impale the nem.

Or you can use the nem cannon method. Sticky in nem part the forum

Holding an ice cube against its foot or directing good flow right at it will cause it to release

Nem cannon!

I'm having mixed results with the nem cannon. Sometimes it takes a week of me adjusting it, blocking light from different directions, getting under the sponge with ice water and just generally trying to annoy it. Other times, I set it up and 10 minutes later the thing is halfway up the tube.
But it still doesn't seem to be a magic bullet, unless I'm doing it wrong.

At this point, I have enough BTAs that I'd be happy with a way to kill them just to get rid of them. I have a QT full of frags that I won't move into the DT until the anemones are under control.
