That's staghorn, BBA does not branch like that and does not have large filaments.
Generally, bioloads that are too high, folks stirring up the soil(if they use it), or stirring upm the gravel etc, then not following it with a large water change afterwards will induce growth, urea also induced growth.
Excel pipetted on the leaves will help, I'd just trim the leaves personally.
1.5x the suggest dosing on the label, and a 50% water change etc.
Clean filter also.
