ID help needed. Growing on coral

[reeferKen]

Around the base of the trumpet coral, right where the green flesh ends and the skeleton begins there is thin brown ring. This ring has stings of clear white that grow up super fast, covered in bubbles. Sometimes it will fork off into two clear forks. I have tried q-tip hydrogen peroxide with no luck for a few weeks. Tried manual removing with the sharp end of a toothpick with no luck. I can't seem to kill it. Any ID ideas, thanks

Can you post a picture that’s not blown out with the blue lights.

Best my camera could do, not much to see but a few clear strands with bubbles embedded in them. I will vacume up the clear strands like in the photo, but They will start to grow right back after a few minutes under light, Amazingly fast. They grow from the thin brown ring described that hugs the green candy cane flesh, not on it, just a hair below the flesh. Peroxide q-tip sure has not killed it. Frags are in a small bare glass jar in QT. Just 100% water changes every few days. Thanks in advance.

I have no idea. A clearer picture always helps. Kill the blues for a good pic.

But it sounds you may be stressing the coral a lot by doing this and by doing so, may kill the coral. Does the forking bubble thing bother the coral at all?

Yea it could be slime corals produce, or it could be some form of hydroids

Try shooting it with whites only on. Or get a sample of it on slide and snap a pic or video under a cheap 100X microscope. There are thousands of
Algae types.

Does it only appear with day light cycle?
