HELP white web like fibers floating in tank

[adamsfour]

I have a string like white filament/ spider web floating in my tank. Water is clear and coral seem happy. Alkalinity is 11.3, calcium 395 , mag 1350. Any idea what it is and how to get rid of. I recent removed an over grown coral and was wonder if it’s a stress reaction by the remaining portion of the coral

Corals can definitely slime but so can certain pests. Can you get a pic?
