Macro ID needed

I've got this macro growing anywhere it can attach, including glass, LR and substrate.

Looks like dictyota to me. Very tough to get rid of. Don't pull it from rocks and sub in the tank, it can spread very easy.

Too late... Anything that eats it?

No, not with any effectiveness. I had a pretty bad case of it in my one tank. I tried to clean the rocks and frags the best I could with a hydrogen peroxide dip. Eventually I just started over with new rock and sand.

If you're still battling this, Algaefix Marine wiped it out in my tank, will take 1-2 weeks.
