Why my arco skin bubble/bounce?

[-JoJoReefing-]

Most of my arco have bubbles under the skin all over the place; and some of my zoa looks like mutated zombie; the plate coral gets star tips, and hammer tips are bloated. Seems some arco become green. I tested the water a while ago but everything on track. Alk around 8.5, Cal around 430 and Mag around 1300 always stable. I wonder if this is bacteria issue? I also heard today this could be microbubble getting into the tissue. Anyone had similar experience?

Send an Aquabiomics test in. This is likely a bacterial process, possibly from Planktotella.

That’s amazing! I have never seen acropora and also multiple lps get the neoplasia type bubbles everywhere. Unfortunately no one has a solution for this issue. Make sure the big three are in line and make sure there is no dosing going on that’s not needed.

My guess is water chemistry, like a presence of an element or heavy metals in the water, or high nutrients, or bacterial infection. Many times the high nutrient systems tend to activate bacterial infections. Or other pathogenic microorganism. We also know that lack of water motion can cause anomalies on the corals tentacles' projections. Lack of proper light qualities could also have negative influence on coral immunization. Or a combination of all or some of the above.
Some have reported those anomalies and they seem/look to be gas or water retention. I don't think those projections are tumors. They would have to have the presence of a solid formation.

I just got this video mentioning the problem.

Hi!

I have the same issue in my tank. Were would able to find the cause ?

I sent an ICP test but results were fine.

No we couldn’t find out the root cause, recently it is getting slightly better though we don’t really change anything in particular. Started using moonshiner method to dose elements, which seems to help with growth and color, but the bubbles remain on most of the frags

This happens sometimes and we're not sure why (for a bunch of examples and speculations as to why this might happen, see my post in the link below) - it doesn't generally seem to cause issues for the coral, but the bubbles sometimes pop (reportedly leaving the corals more vulnerable to infection as the pop heals), and, in at least one case I've seen, eventually developed into a hole in the coral (though the colony itself was still fine).

What is your salinity? Did you ever have a large salinity swing?

It’s very odd. Most of my acros have bubbles. The growth of some others are quite odd too..

Bubbles are appearing on rock flower anemones and acanthastreas.

Hammers and frogs lost their natural shape…

I think I read a post from @Epic Aquaculture discussing this. Somewhere on here was a thread regarding this.
