I wouldn't add it. I've got freaking aiptasia, they're bloody indestructible. I think mine were introduced with live sand. If you have no aiptasia I wouldn't do anything to jeopardize that. If there are critters in the sand you could sort out some beneficial ones like amphipods, mini stars, and snails by picking them out of the gunk. Try dumping it bit by bit into a largish white bottomed container with some clean saltwater so you can see the critters to pick them out.

I would add it, but I dont have a reef tank.

How do aiptasia propogate? I'm wondering if having it in the sump is a threat to the main.

They propagate by each teeny tiny bit that breaks off of them, even violently, becomes another anemone. So there could easily be bits of aiptasia in the gunk. Maybe quarantine the gunk? If you don't see aiptasia in a short period (they grow fast) it should be ok.
