Green algae

[JamesWeaver]

It started to come when I noticed my first spots of coralline algae. Now it is all over my refugium and started to show in DT. Can coralline be green? It is very hard to scrub off. The picture of the sump there is a lot of chaeto that is broken off even though it looks like hair algae it’s not just some debris

Yup, coralline can be green. Mine came in green before transitioning to purple.
