What is this?

Hello Friends,

I have these green balls growing on one of my live rocks. This piece of live rock is about 2 months old and I noticed them about a month ago. Now they are very noticeable because they are getting bigger. Can someone tell me what this is growing in my tank. I tried to take a clear picture but I have not had any luck. The pic is attached.

Thanks in advance ;D

 

bubble algae, can you remove the rock its on? If so, manually remove it and torch the area

 

I can't see the pic but the description sounds like bubble algae and I trust Cosmo

 

Thanks Cosmo, Oldfishkeeper, I can remove the rock it is not a problem. What exactly do you mean by torching the area. Do I discard the rock with the bubble algae, or do I drop in bleach water and let the bleach kill everything on the rock. Once I rid the rock of the bleach can I put it back in the tank or is it best to rid of the rock completely.

Thanks

 

I just dealt with this issue and this is what I did. I removed the rock and used some tweezers and a razor blade to remove the bubble algae, I then literally got a butane torch and torch the area, then rinsed it under hot water. Just watch if you "pop" the algae, that liquid has spores that will make 1000s of them.

If its a small rock, I'd just bleach it, cure it and return tough. My rock had other corals on it I liked so that wasn't an option. Emerald crabs may eat it, but they can become a nuisance themselves.
