Hydroid and Algae Confirmation

[Petrichor]

My tank is right in its awkward teenage growing years, aka the algae bloom phase, so I'm looking for advice on whether I need to take action or if a hands off approach is better.

Picture 1: I just want to confirm these are hydroids and not aiptasia on the inside of the outer edge of the red circle. Would Aiptasia-X work on them, or is super glue the best method? Or do I even need to do anything? Might they just phase out as the tank matures?

Picture 2: Is this green hair algae (ignoring the chaeto and diatoms), or something else?

Yes, hydroids and green hair algae.

I took the hands off approach for both, for the algae it fixed itself eventually. I had a different species of hydroids and never fully eradicated them so I have no advice on that front.

Thanks for the reply samnaz. The hydroids definitely weren't there when I started the tank, so I think I'll just try increasing flow on the rock and reducing food for the week and see where that takes me. Hopefully they're just (temporary) growing pains for the tank.
