Id?

So I’m adjusting my flow around to try to clear up some dead spots in my water and it’s moving my sand and I am finding these in various spots buried in my sand bed..anyone have any idea what it is? It’s white and looks like waded up string

Egg masses, likely a snail or nudibranch?

Would have to be snail..what should I do with it?

Eggs are generally not a problem, whatever you like will be ok. I've never bothered when my cleaner snails lay eggs, just leave them where they are laid.
