Bubble algae. Emerald crabs. They will make quick time of it.

Tell that to my emerald crabs.

I don't really have a bubble algae problem, just a few clusters here and there, mostly on the ulva for some reason. I try to be gentle removing them, but they usually pop.

It's been 'common knowledge' that popping them spreads spores and causes more to grow.

However, I've read recently that this may not be the case. I'm not ready to take someone's word on that, since I haven't seen many people refuting the commonly held idea.

Although... if popping them really caused more to grow, I should have gazillions of them by now. (I don't.)

Ha ha. Your crabs are probably to well feed. There like "algae? F that. Wait ten mins. The guy will feed the fish. We'll eat scraps and poop for hours." They should take care of it. Maybe pick the craps up and plop them on the bubble algae. Force feed.
