Please ID and what to do

[Oscar Bravo]

I have this algae growing fast in my tank. Looks like grass not long. It starting to take real estate over the rock and on my sps. Anyone know what it is and how to kill it?

Looks like GHA, if you can take out the rocks one at a time & pull it off or use a tooth brush to scrub it. Some use Vibrant to get rid of unwanted algae as well. There are also hermits & snails that will eat it.

Yeah taking the rock out will be a lot of work. I am going to try turbo snails hope they eat it. Also I try injecting kalkwaser and it burn it! But I can use a lot because jumps in alk.

This is past the Green Hair Algae stage and becoming Bryopsis.
Reducing white lights, pulling by hand and adding either flux or liquid vibrant will be your answer.
