Worms eating exoskeleton

[JaimeShan27]

I have discovered 3 different types of worms burrowing into the exoskeleton of one of my hammers and my lobo. The hammer has a perfect circle and the lobo has jaggered erosion on the bottom and sides. I have just dipped in dip x again.
What can I do to stop this from getting worse?

Not sure if you can see part of the worm but if you can have you consider tweezers or a pick to kill them? If its not through to the coral tissue then maybe try a bit of Kalk paste? Same as if you were killing aptasia. Just ideas but other than tweezers I haven't personally tried these methods.

I saw a video aci aquaculture had on them. They are some boring worm that will eventually kill the coral. He tweezered and cut them out
