Red fluffy algae

[TriangleReef]

The bubbling on this tells me it may be dinos but the red fluffy colour and texture is confusing me. This tank most likely has little nutrients as it’s got three bridled gobies and caleurpa. If anyone could help me out with how to get rid of the stuff that would be greatly appreciated
