Emerald crabs
Emerald crabs and syphon. Don't worry about popping them. Crabs pop them when they eat them, so its not as big of a deal as most people think.
I'm in the minority here but I actually don't mind a small amount (emphasis on small) of bubble algae. It looks cool and, at least in my tanks, has never gotten out of control.
Gently remove the bubbles without popping them is the best method I've seen the emerald crab will clean up the rest of the small bubbles you miss. Just don't pop them or you will have a giant headache![]()
So emerald crabs are effective? I've tried manual removal for months now, and I can't get it under control. It seems to be getting worse. I don't have any (detectable) excess nutrients, and feed very sparingly, and do weekly water changes. It is driving me insane. I also have pink cotton candy algae, which combined with bubble algae is my own personal torment.
