Algae identification based on some pictures.

[Krauss]

Hello everyone!
I have a marine aquarium that is about 7 years old. A few weeks ago, I bought some new corals and changed the lighting a bit by adding a Fluval Marine 3.0
Since then, the algae in my aquarium have exploded, algae that I have never had in my aquarium. Can you tell me, based on the pictures I have attached, what type of algae these are?
Thank you for the help.

What light did you have before?

What light did you have before?

I had a hybrid system. 2 x ATI Coral Plus T5 39W + 3 x Tunze LED Marine 10W
I replaced those three TUNZE with a single Fluval Sea Marine 3.0 LED 46W.
The aquarium is a 240 liters with soft corals, 4 fish, 5 Trochus snails and one BBA.
