Strange white coating

[x19]

This seemingly hard white substance has starting growing on some of my rock. Any ideas what it is?

Right in the center of the frame:

As you can see in this shot it is covering a big chunk of rock:

That looks like some type of sponge to me.

That looks like bleached coralline which can happen becuase it was exposed to air for a mere minute or two.

Hmm ok. Can it be delayed? It was definitely exposed to the air for about 30 minutes, but that was last Sunday.

Now that you've boxed it in so I can see it.:D It looks more like bleached coralline.

:D lol yeah I think what you though was a sponge was just epoxy holding the rocks together.

The coralline will die if exposed to air, but it will come back over time. No worries.

Coralline needs good alk and calcium levels. During water changes I like to baste it with water every 30 seconds and it does help keep it from dying.

Yep, hoping to add my first coral tomorrow and I've got some Zoas coming from Cageburn on Monday. Incidentally, I've got a Nikon D90 dslr but these pictures were taken with my iPhone 4 :-)

wow I think that is impressive for a phone. But that is coming from a guy whose phone can only be used to talk on.
