reef tank 2.0

This is the only "bubble" i have seen in my whole tank. This flowy bubble is attached to the sand. It's maybe a 1/16 of an inch in diameter. It stationary, but yet sways in the flow.....never leaving that spot.
is that bubble algae? I can't get closer with my phone, it's towards the back of the tank. if you look super duper close, you will see a mini "stem" at the base of it going in to the sand
