Hello so I just returned from a very long vacation about 7weeks. I have not tested my water nor done waterchange. Had someone feed while I was away and pretty much it.
I have a 40g LPS dominated reef currently running a Fluval 407 filter. And I come back to this algae and I’m guessing bubble. Can I get some help getting this back to normal please
