Green bubble algae

[Coralgurl]

Found some green bubble algae growing in my tank. I've read through some information and would like to know best easiest way to remove. Should I remove the rocks and chisel off or can they be removed in the tank. I can only see 2 bubbles, is there likely more? I haven't touched them but assume they are attached.

Whenever I see these bad boys pop up, I just siphon them out. I use a piece of rigid airline attached to regular airline. I've cut the end of the rigid on an angle so I can get under the bubble and scrap the holdfast (algae root) off. I turn my pumps off, start a siphon and carefully get them out, just don't pop them.

If you can easily get the rock out, you could carefully use tweezers to pull the off, then rinse the rock off outside the tank before you put back in.

emerald crabs eat it

I had to remove one bubble.

I pulled the (so small it fit in a coffee cup) rock, plucked off the bubble (rupturing it in the process) and then set the rock in a mixture of 1:10 hydrogen peroxide to saltwater for 10 minutes to kill any spores.

That was four weeks, or so, ago. I haven't seen any others since then, but I think the time span is too short to know if it truly worked or not.

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.

+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 !!
