Is this dinoflagellate?

I noticed this growing on one of my live rock. So far it looks to be the only area it is growing. I would like to take care of it if this might become a problem.

Thanks

I think it may e be byprosis or gha. It's not dinos.

Thanks. I suppose i should start dosing tech M to increase magnesium before it becomes an issue.

Looks like some form of macro algae to me. Its not GHA or bryopsis.

Bryopsis.

It actually looks like caulerpa to me.

I google imaged caulerpa and im not convinced if that is it. I suppose i can keep an eye on it and see if i can definitively confirm what it is.
