Red bubble

[pzunker]

So I am getting an outbreak of red algae all over and I couldn't figure out why till I noticed one of mu red bubble algae was broken open. Im noticing more and more red bubble. What will get rid of those without spreading spores? Is there a certain kind of crab??

Emerald and ruby crabs are supposed to eat bubble algae, but of course, in nature there's no guarantee.

Mr saltwater tv has a good video on YouTube about removing bubble algae. I just looked it up cause I had a small colony in my tank. What ever you do don't pop them. I just gently freed them with my turkey baster then sucked them up.
