One thing I'd like to add is, if you keep your circulation pumps running, remove some manually and it starts floating around the tank. Some will get stuck in rocks, etc...but most ends up stuck to the intake mesh of the pump, where you can then remove the pump and clean the intake. Makes it easier than chasing individual pieces with a net. Alternatively put your net in front of the pump and the bubbles will be blown into the net.
Used Vibrant at the recommended dose. It certainly helped kill my bubble algae and I understand why people use it. Had a pretty bad infestation because I ignored it until it was a bigger problem. Unfortunately, I used mine one year in or so when my biome was still maturing and it knocked everything back to the stone age. Once it died off, got a bunch of ugly brown algae, then a dino infestation, then diatoms. Lots of snail deaths too, which could be attributed to the nitrate release/toxicity of the dinoflagellate/Vibrant all at once. Was pretty demoralizing to go from one problem to another.i still have a bit of bubble algae but now my urchins and crabs take care of what I don't get. I don't want to make this thread into an anti-algaecide crusade, just make sure you try other options first, read directions, and expect odd effects. Also, if you have macroalgae in your refugium, it'll melt.
In the case of bubble algae an ounce of prevention is worth a pound of cure, probably quite literally lol. It's a lot like aiptasia in that respect. Ignore at your peril
