Cyphastrea brown bubbles

[Barracuda85]

Good day to everyone!

A couple of weeks ago my cyphastrea started making those brown bubbles, they seem to go away on their own and pup up again on another spot on the colony. The coral seems healthy, and doesn't seem to be bothered with that. This coral has been with me for years, and no changes were done to lighting, parameters etc. Does anyone has clue what this could be? Thanks in advance!

Weird. Never seen that on any of mine...

May be mulm. Take a turkey baster and give surface VERY GENTLE bursts and see if it dislodges. if so, increase flow TOWARDS area a little more

Thanks for the feedback! Tried just that, won't dislodge. Seems to be part of the coral. The bubbles seem to have shrunk a little, ever since the lights came on. Just thought maybe anyone else has observed something like that, I am not too worried about it, it's more the curiosity part...
