Algae on my live rock?

[TexanTrail]

Can someone help ID this stuff growing on my live rock? Started cleaning up my DT (nitrates WAY too high). Got them down to reasonable levels and this started growing on my rocks. I also started dosing Vodka at that same time.
Thanks in advance for your help. It's about 1/8 to 1/4 inches tall.

The color almost suggests a coralline algae, which would indicate plenty of calcium in your water. Kinda looks like a 'turf' algae. If it stays short and you don't mind how it looks, you may want to keep it for nutrient uptake, oxygen production and herbivore food. If you hate it, or it gets out of hand, you may want to add an herbivorous fish, like a tang. And there's always the 'nuclear option'-an urchin.

And there's the usual recommendations to correct the root cause, excess nutrients, etc.

It doesn't look like a cyanobacteria, which can pop up with carbon dosing. Whatever it is, conditions in your tank are ideal for it.

Are the plants "crunchy"? It looks like Jania to me, which is a calcified genus.

I was thinking jania as well
