What the @#&%?? Birdsnest Bubble Growths
 

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. :biggrin:

(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?

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? :evil:

:redface:

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. :eek:
Keep us posted on what you did and what happened.

It's not a toomah!




Sorry, I had to...

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.
