Acropora tissue bubbling. Disease?

Basically it is an environmental imbalance that the coral reacts to by changing the crystalline structure of its skeletal matrix.

The aragonite polymorph is structurally more robust compared to the calcite polymorph which is why we are hearing about flow being suspected. ie the "windswept" growths.

Exactly why the blisters occurs I'm not entirely sure but I feel as though it may be some sort of localized gas build up between the connective tissue and the skeletal matrix due to the excellerated growth rate of the calcite polymorph.

Just my 2 cents

Wow, before the hyperplasia kicked in hard, we had the "windswept" growth thing going in our more delicate acros.

Thanks very much for contributing here.

Interesting, in my experience the thin branched acros, walindii, carducc, derawenensis exhibited the same thing. Growth tips would shoot up an inch over the course of 1-2 days but we're so fragile they would disintegrate if disturbed.

Yup, carduus and echinata here.

Such a relief to know what the deal was.

Any more updates on this very interesting thread please?

Hello, what a brilliant thread, I’ve been dealing with this issue for few months now, recently came across this thread and I’ve been reading it multiple times now I’m just wondering if

So... I'm not sure if this has anything to do with anything, but I took 71xlch's advice, went back to basics, and am now dosing equal amounts of a balanced alk a calcium supplement. I thought I'd see a massive spike in my calcium levels, but I didn't. In fact, things started growing so fast I've had to up my dosing rate of both by 20 mL/day a week for the last three weeks.

no new plasias have formed on my corals since I did this, and in fact... my worst hit colony (the one pictured on the first page) has branched off several brand new, completely healthy looking growth tips from one of the worst branches. My pink lemonade, which had one tip out of 20 swell up like a balloon a couple of days before I changed my dosing regimen, has returned to normal.

This is by no means a smoking bullet, and my 'Big three' levels were never really that much out of balance. However, I'm adding huge volumes of alk and calcium supplement to my tank relative to its size, and I was adding twice as much alk supplement per day as calcium supplement for the better part of a year. This means I was also adding twice as much sodium to the tank as chloride. Go figure things would only start improving when I'd do 3 or 4 large water changes in a row. It's not something we have a test for (sodium/chloride balance), but has anyone else experiencing this examined their dosing regimen? Do we know what the chemical consequences of adding twice as much sodium as chloride might be? Or what that might do to a coral?

Hello, what a brilliant thread, I’ve been dealing with this issue for few months now, recently came across this thread and I’ve been reading it multiple times now I’m just wondering how long did it take for the problem to disappear for you from when you started dosing equal amounts? Also does the photos I attached look like the same issue you had? Polyps tulliping and small bubbles on acros.

Hey all.

I hadn't checked in here in some time -- I just want to corroborate something.

Asylumdown has likely figured out the problem I had as well. We ALWAYS had to dose heavily uneven amounts of calc and alk. We had some serious growth happening in multiple colonies when I started needing the uneven dosing, and the hyperplasia quickly followed.

We've since torn down and will be restarting, but seriously, hats off to this man.

Just looking at that tank, you can see the result of that quality of reefing.

*clap*!

Hey thanks for the great research, from what I understand you had to restart, did you get reoccurrence after this? Or was it definitely the uneven dosing? Having the same issue I believe, I posted some photos if you could check and see if that looks like what you had to deal with? Thank you.
