What the @#&%?? Birdsnest Bubble Growths

[AJ_77]

Just saw this tonight on my frag of pink w/purple birdsnest - anybody know what this could be?



Here's a close-up of the action - can't quite tell if the "bubbles" are hard or soft:



Ca = 370 / Alk = 7.5 dkH / Salinity = 1.026 / Temp = 81. All other corals look normal. Any useful input is appreciated.

(Gonna go try to post this on RC as well.)

good god, i have no clue but it looks mutant

Could it be sponge growth, if soft?

[AJ_77]

Crap, I think it's the skin of the coral itself.... d@#n it. A guy on another board suggested it may be low Alk, and I re-tested, and got a number lower than what I thought I had.

Dripping more kalk right now...

It looks like the coral is detaching from its skeleton, doesn't it?

[SeaHorse_Fanatic]

Yeah, it sort of does look like a bubble forming below the skin. Good luck. At least you were vigilant enough to catch it early.

Hello,

Wow that's one freaky looking piece.
Keep us posted on what you did and what happened.

Kalk won't realy bring up your Alk in my experiance.. I would use baking soda to raise it up to where it should be.

Baking soda will lower pH, but will definitely raise alk.

Here's an article on alk and calcium:

I have the same thing, but just one big bubble. It's been there for over a year, and my coral has dubbled in size. Everyonce in a while they pop and then come back, and no other bubbles in my tank, so it isn't spreading.
