bubble algae just below candy cane coral head


New member
I just noticed bubble algae growing just below candy cane coral head. Its just a couple of spots

How do I get rid off it? Can I scrub it outside the water? Should I dip it in iodine? Would that help future outbreaks?

If its growing in one place what are the chances its growing somewhere else? How can I keep it under control?

I have 72 gallon bow front and I change 5 gals of water every week. :worried:

Pull it out and pry off the bubble algae with a toothpick or tweezers then scrub with a soft toothbrush in a bowl of tank water. Try not to harm the flesh of the coral.

I use a syringe or turkey baster and just suck them right off the rock. Find what works best for you, just try not to pop them. Its not the end of the world if you do, but it can spread sometimes if they break.

You'll probably do more damage trying to remove it than the bubble algae would ever do just staying put. It's harmless, mostly, just a nuisance. It's also a phase. Tanks get it down and again, it runs for a month or so, then goes away and you get something else instead...
