Bounce Acros???

[Reefer93105]

Can anyone chime in what these bubble are? Bacteria? My Hawkin's Echinata at home have done this before many years ago and it disappearedon it's own. Now it's happening agian in my prop system. I only notice these on smooth skinned acros. These acros are doing fine and been like this for almost 3 weeks now.

Wow that's interesting never seen before tagging along

How's the flow in the tank? Any differences in parameters?

Wow that is strange. Tagging along as well.

Parameters are fine ALK 8.3 to 8.6 dKH CA 425 to 430 MG 1380 to 1410. No issues with nutrients. Flow is good.

Had this happen in my acros before to. Not sure if it was the cause but I had red bugs and after killing them things went back to normal.

No bugs here. Acros are healthy and happy. These acros are in a 1370 gallon prop system. Close to a hundred acro colonies in there and they are all doing fine.

Looks like either Neoplasia or hyperplasia. Almost like a tumor growth of cells, causes aren't really known but some speculate that unstable calcium levels are to blame. Do you use 2 part or a CaRX?

Nope GEO 1218 ca reactor here. My CA always between 425 to 430. I test my waters twice to thrice a week.
More like hyperplasia. I have a frag that have neoplasia. Same system but different tub.

Ive had this happen before, not sure the cause but it went away

 

[Reefer93105]

No one really knows for sure why it happens. Second time I have seen it happen in two different systems.

I have had this happen a few times in the last ten yrs or so. It eventually went away and all was normal again. I just kept parameters consistent, was using a calc reactor, nothing was out of wack when this happened fwiw. No red bugs, aefw, just an odd occurrence imo

Bounce acros lol. Sell it for 1k per frag
Seriously though, I've seen this in other tanks over the past 15 years, and in my own systems . There are numerous threads on it. Search blisters on acros, bubbles on acros etc. Lots of speculation but no definitive answer.

Just a side note: I can't believe the abbreviation for "Laughing My Blank Off" is actually censored

 

[whatchamacallit]

I thought I read somewhere before that it usually happens before a spawning? Maybe I'm wrong though, it had to be atleast a year ago I read on a thread.

 

[rock_lobster]

Mine did that when I raised the magnesium to quickly once. It went away after about a 2 weeks.

 

[ReefChef27]

I've heard this happens in lower lighting situations sometimes

 

[evolved]

I've seen it happen a few times before to others, but typically is due to high Mg or a spike of it.

Interesting, first time I see this on Acros

Assuming no pests are involved. The coral is increasing the tissue's surface area so they can increase Zooxanthellae density so they can produce more by product of energy production so they can increase their energy store levels. They could be about to go on a big growth spurt so they are increasing production or they could be developing eggs and sperm and need the extra energy for the egg or sperm production. I have had this before in those two instances. If you notice in the pictures the largest concentration of the expanded tissue are clustered around the growing tips where growth will come from and for the most part not closer to the base of the coral.

I've had this happen in my old tank, which I have since taken down due to a move. Once it happens and you do a little research you'll find its a lot more common than people think.

Very little information as to what actually causes it but lots of guesses. Your only hope is some people have reported it goes away in time. Mine never did and it got so bad the coral tissue became deformed. I had a thread on another popular Reef message board about it.

 

[WetWhistle]

I have had this off and on for decades now so this is not rare occurrence for me. For me it always comes before a big growth spurt or gamete production and goes away right after the growth spurt or releasing of gametes. It doesn't happen every year but it does reoccur every few years. I would say that is a pretty good correlation between the two in my experience. Plus about 10 years ago or more they did a study's on this and came to the same conclusion. This was before online forums were popular and it would have been published in a magazine or book and not online unfortunately. So it is hard to find information on it but I will see if I can find the article at home, but I will probably not still have it. I think it was done by ether Alf Jacob Nilsen and Svein A. Fossa or Julian Sprung, J. Charles Delbeek or Eric Bornemen in one of their publishing. But I could be wrong on who published it as it was a long time ago. Mine never does any damage and just goes away one day as quickly as it came. In every case the coral was larger or more rarely it released gametes after it went away.

OP did the coral suffer any damage and had to heal recently or any color loss? I can also see those two situations being applied to decrease healing time by increasing Zooxanthellae production.

@Jimbo if yours kept getting worse it could have been a bacterial infection or virus. Mine never got any bigger then the ones in the pictures and went away after a month or two. Did you try dipping in super selco iodine? Hopefully the OP's is not like yours as that would seriously suck.
