Coralline

[Rmckoy]

When coralline is exposed to air does it die instantly or does the Florescent orange colour go away ?

I had to lower the water long enough to fix the leaking bulkhead that’s had salt creep for a few months .

it was a little wetter than I would prefer and why I tackled this job today

IME if it's orange like that, it's dead already. Upside, right conditions it will be right back!

If it’s exposed to air ( water changes etc ) some always turns orange .

That's the big question, how long has it been out of water? Again IME any real length of time it's death.

Roughly 2 hours …
Long enough to drain below the overflow . go to the hardware store after noticing I was out of Teflon tape .
take each fitting apart and clean ,
Apply tape to the threaded parts and install the bulkhead with new gaskets .

More than likely dead then. You'll know in a day or so, the color will pale and turn whiteish.

Not really I have most of coralline on top of my hang on back filter.

unless the filter is off. that CA will stay alive as water is constantly running

This. It's still covered in water, big difference.

I know but op mentioned of losing color on CA during water changes, I shut off my filter on a water change.

 

[Danroo]

Never mind didn’t saw the 2 hour period, yeah my max is 10 mins.

But that process takes I'm assuming minutes versus hours in the op's case.

When exposed to air and used a water change as a example .
the time it was exposed it a little longer than it would take to do a water change . But notice even with water changes . Not all but some exposed to air always turns bright orange .
I’m not worried as I have tons to absorb alkalinity

When I do water changes some of mine gets exposed to air and turns bright pink but then seems to purple back up again in a few days. Probably out of the water for 15 minutes maybe 20.

The only time I lost CA was when I moved, it came back rather quickly. For some reason it liked plastic so much.

 

[Who me?]

No. It is not dead. Coralline will survive several hours in nature during low tide while exposed to the air. The color will change temporarily but it will not die that quickly.

This ^ the exact answer I was looking for .
