Hey wondering if I should be worried about this dark brown stringy stuff in 6 month old tank, I blow it off and it comes back almost immediately mostly on sand alittle bit on rock scape, will it eventually go away or don’t need to deal with it

You're going to need to post white light pictures to get any ID.

Cyano. That is what comes with every tank and fish. Nutrients and light feed it.
Got a bit of that in a couple tanks.
