That’s hair algae what are your nitrates and phosphate levels I’m guessing they are high. Once you get them in control it should die back naturally. You could also add something that eats is snails or and urchin which are absolute algae machines.

That’s hair algae that is now covered in dinoflagellates

Those are GHA. Whether Dinos are there, I cannot say.
In addition to controlling your nutrients and adding CUC, you should do some manual removal.
