Acro Ballooning, Swelling, Blistering=odd calcification....

I keep low dkh and have seen it in my tank. 7.7-8.3 dkh.

Maybe mag problem . Like expotential growth but lack of balance between alk,mg and ca. Which leads to abnormalties ?

just an idea.
 
I have a similar problem w/ an "acro blister". Same coral, same place, comes and goes randomly but I cannot correlate to alk or calcium. I don't test mag & only dosing is 2 part as well as some iodine. Blister is close to the base of the blue tip acro.

This is a great thread that will likely be missed by the majority of folks here on the board! I have never seen this. If your corals develop the blistering and then STN, I think this is a fantastic thing to bring up. I have heard of alkalinity burn but never a blistering that started from the skeletal matrix. I have a tenuis that the tips burn all the time. I can't figure out why. All of my parameters are normal.

I have kept a lot of acros for many years and the only time I would see a "blister" was when a new branch would form from a new radial coralite.

I'd be interested to see how this pans out.

Its not a new thing by any means.Its just not talked about very often.but it seems to me most of the people that have this problem are dosing something,altho the thread i listed above has links a few pages later to people that were not dosing anything.I had this problem a few years ago on a few pieces,but i also was messing with Zeo at the time,so i thought that had caused it.Theres alot of guesses but no real answers.
 
So far the only thing in common is that everyone who has posted thus far has a very nice tank with thriving acro's. Could these corals blisters possibly be filled with egg/sperm and preparing to spawn? Shooting in the dark, I have no idea :)

Not so, sorry I didn't elaborate.

When My acros did it my tank was doing very bad, every frag that went in there would loose PE in a week and STN in a month about. The only growth I ever saw was the blisters.

I am very happy to say those days are behind me, but I do still get some blisters from time to time, they seem to go away on their own though.

i remember reading some threads a while ago with some anecdotal evidence suggesting that low magnesium was the cause of this.
 
Which goes back to my suggestion. My mg has been low th elast few months 1100 tops Maybe theirs a reaction to mg supplement which is mag flake.

I had some digitata balloon at the growth ends due to a salinity change from a topoff accident. Maybe something chemical affecting hydration or fluid uptake? But it recovered when salinity returned to normal...

Its bone cancer man.:D






Lol ! just kidding.:)

Could be just elevated Alkalinity...........PEACE

You may be a lot closer then you think :D Check out those links I posted :D
 
Yup its calicoblastic epithelioma, skeletal cancer....

The cells found in the tumor resemble the more metabolically active and rapidly dividing cells of the growing branch tips, and like the branch tips, also lack the symbiotic algae. The epidermis covering the tumor also loses the mucus secretory cells that help remove sediments from the coral surface. The result is that sediment accumulations lead to tissue death and invasion of the skeleton by algae and boring organisms.

The presence of the tumors on a branch is also associated with a decrease in, or halting of, branch tip growth, suggesting changes in the transport of nutrients in the colony. This locally invasive abnormal mass of tissue and unusually porous skeleton grows faster than the surrounding normal tissue and skeleton. It proceeds to destroy the polyps and cause the death of the coral tissue.

Unknown why it happens

The cause(s) of neoplasms in hard corals are unknown. Probably mutations of the genome and/or programmatic changes in gene expression of the coral cells are responsible for these skeletal anomalies, but whether a particular agent, such as ultraviolet radiation, is responsible for a particular mutation has not been determined. Additional studies are needed.

This is why the skeletal pics from Kip looks like they have threnches in them, cancer with the inclusion of borrowing microbes.

Calicoblastic epitheliomas are capable of damaging portions of coral branches, leaving them more susceptible to invasion by boring organisms which can lead to increased breakage and fragmentation, in addition to destroying the normal polyps by which the coral produces eggs and sperm for sexual reproduction.

I recommend cutting off afflicted areas and tossing them, then observing if they grow back afflicted again. If they do, then its probably key'd into the gene of the coral.

 
Still up for checking out some samples though? I'd curious if what we're seeing is this, or something else. Eric Bornemen told me not a lot of research has been conducted on this one.

Heres the link to what i thought was a good answer to the problem by Olin near the bottom.Also a link for when invincible569 went through it.If you have not read it yet,i think the problem was talked about for a few pages further and more links.
I myself think its either a response to light or as put, the corals are just taking in more than there getting rid of.

Yes, make sure all water parameters are leveled. My Mg and salt levels were low. Make sure you test accurately and have your fish store test for you too.
 
A bit different but I thought I should state it. Last month I had an acro coral that had one of the tips on it appeared to be melting. it finally dropped that section ( i think) and left a indent in the tip which appears to be growing back again. Any one ever see this before and I did not get pics for my camera could not capture it.
