Green bubble algae

[emerald crab]

They're difficult to fight, if you have them just on a small rock, kill the rock. I had to learn to live with them.

dumb question but.....have you tried emerald crabs???

+1 for emerald crabs. Eats any that ever pop up in my tanks.

Well I got lucky, it's easier to see when the lights are dim, it was on the side of a dead coral, so out it came. Good to know about the crabs if any more show up! Thanks

Yes I did. They eat them, but they rip them open and spread the spores. Foxface rabitfish eats them, but not in quantities. In other words they don't make a dent in population. Tuxedo urchins won't touch them as long as you have coraline algae in your tank.
They need very little light and very little nutrients: nitrates not detectable, phosphates 0 (hanna colorimeter).

My tank has lots

I read somewhere that algaefix marine will keep the spores from growing if the bubble is popped ,so I might start dosing that for a week and then go to town popping bubbles. Hopefully with continued dosing for a while after will kill all the spores and no more bubble algae !!

Or you can learn to live with them like I did.

a sharp razor blade can also cut them off without popping them

Depends how smooth your rock is.

The bubble alage is in all the annoying spots a razor can't reach
