Aiptasia or Something Else?

It doesn't look like aiptasia I've seen before, but not sure what this is. Some kind of algae maybe?

Some type of macro algae , I would remove unless you cool with algae

I'll give it a dip to clear it up. Thanks!

If its algae you might want to just focus on your nutrient levels. Some dips only kill certain algae. So if you know the dip you have is right for this algae type then you are good to go.

Looks a little like Dictyota, which is usually seen as a pest, but more pictures would help with identification.
