VTBig053 December 14, 2017 Share December 14, 2017 Looks like bubble algae. You can remove it manually but be careful not to pop the bubbles. I believe emerald crabs will eat it as well. Link to comment Share on other sites More sharing options...
Jon Lazar December 14, 2017 Share December 14, 2017 Definitely bubble algae. I would pop the frag off and throw away the old plug. Then pick off every last bit of valonia before regluing. You need a biological control to keep it from returning. Emerald/mithrax crabs will eat it, but slowly. Rabbitfish will likely eat bubble algae. I had a Desjardini tang that loved it.

zygote2k December 14, 2017 Share December 14, 2017 Everyone says "don't pop them"... How do you think the rabbitfish or emerald crabs eat it? A common algae found on drag plugs. As started previously, pop the coral off the plug and discard the rest. Link to comment Share on other sites More sharing options...
molcott December 14, 2017 Author Share December 14, 2017 I think I got the bulk of it I popped it off the plug and put it on a new one will pick some emerald crabs later for good measure Sent from my SM-G955U using Tapatalk Link to comment Share on other sites More sharing options...
freshfins December 14, 2017 Share December 14, 2017 In my experience if you resolve your excess nutrient issue the bubble algae disappears. Link to comment Share on other sites More sharing options...
WheresTheReef December 14, 2017 Share December 14, 2017 No need to buy the emerald crab if bubble algae isn't out of control. Link to comment Share on other sites More sharing options...
