Algae I.D help

[SaltLifeMom]

Hi all, can anyone help I.D? I don't want to start any treatment until I know what's going on. Thought it was GHA but none of my cuc touch it. Thoughts?

Certainly a filamentous algae, but these filaments seem wider and stiffer than typical GHA. Sorry, can’t help with weed control beyond suggesting a Mexican turbo

Thanks! It's very stuff. I can't pull it out with tweezers or by pinching. Bubbles a bit under peroxide but doesn't due or turn white. Wierd

I feel like I had something similar, and this was Bryopsis. At first, I didn't know it was Bryopsis because it didn't have the fem everyone was talking about. I added a tuxedo sea urchin and that got rid of the bigger patch which was pretty shocking cause I thought no clean-up crew eats this. I still had many strands of them popping up after the urchin cleaned up most of the patches. I was sick of plucking them up with my hands, so I added fluconazole to deal with most of them. Although, I still got some here and there after a few months. Nothing too ugly.

Follow this thread on how to use Fluconazole. If it is Bryopsis.
