I might have a bubble algae problem

Walking by my nano tank today and this is what I see I think my urchin was trying to sell me something

I had a massive outbreak in a previous tank. I heard it was a hit or miss with emerald crabs, so I ended up buying like 10 and eventually they took care of them all. Tangs wouldn't touch it when it was on the rocks, but when the crabs picked them loose, my tangs would eat it free floating in the water.

Bigger ones do better

You'd make an Emerald Crab super happy. I usually add oneevery 6-9 months... Let it clean up, trap him, and give away.... They've worked for me every time.

Looks like it may be more than just bubble algae…
