White soft tentacles growing in my sand.

[Eyeman313]

Got a problem. 65 gallon fish only tank, been up for about 3 yrs.
No problems until now. Left for one week and hooked up an auto feeder with freeze dried brine shrimp.
Came home to something white, growing all over the black sand. Looks like sponge tentacles. But I can’t get it off the sand or get rid of it.
Any thoughts or suggestions??
