What is this and how do I kill it

It is tough as toothbrush and tweezers won’t remove it. Thanks in advance!

Gelidium.
Takes some work to remove, so might be best to move that clam and any rocks it's on to a shallow container and diligently pick it off strand by strand.. Emerald crabs would probably clean up what's left when you're done.

Also known as Red Wire Algae. This stuff is so annoying. If you can, remove whatever seems to be growing it and try to pick it off manually with tweezers; strand by strand if you can. (some people even burn this stuff off their live rock cause their roots penetrate into the rock.) If it feels like it is too much to do that, get yourself an emerald crab, a tuxedo urchin, or even some snails have been known to eat it. Also, try checking your phosphates at your LFS or using a test kit and doing a big water change before you do anything too crazy, sometimes the simplest answer is the best!

Thank you for your suggestions! I run carbon and gfo and vibrant but it seems not being affected, and removing them manually is so hard. I will give emerald carb and urchin a shot.

Curious to see an update on this. I’ve tried Mexican turbos with no real luck. At first they started eating it and it’s like they just gave up. I was going to try either a peroxide dip or burning it off next

I have used a combination forces of short spin urchin, pencil urchin, blue Tuxedo urchin, and turbo. There is only a little bit left in the crevice now
