What is growing on this alveopora?

[gideon2086]

This brown "stuff" started growing on the center of the piece recently and as you can see the polyps in the area aren't happy. I've brushed it off. I've dipped it. The stuff keeps coming back and spreading further. Any thoughts would be greatly appreciated.

Have the polyps died back in that area?

A pic in white light would help. If the coral has died off and receded in that area leaving skeleton exposed, algae will grow on it. Your best bet is figuring out why the coral is dying/receding in this case.

Thats what I was getting at, if there's die back in that area its algae. Then you need to figure out whats killing your coral.

That is likely the case. The coral became sad when I added a to fixture. My guess is the par was too high. It use to be a dark blue and as you can see has since changed to a light blue.

Upon further inspection... the polyps are not dead.

Updated pics, it continues to spread.

Are the healthy polyps ever extended?

It doesn't look like anything is growing on it, looks like you are getting some bare skeleton from the coral receding.
What you are seeing is the actual corallite.

Alveopora is pretty resilient and could possible comeback from this.

Defiantly bleached also which makes it a little harder.

You are not going to want algae to start to grow on the bare part. That will make it much harder.

You may want to lightly turkey baste that part every once in a while so something doesn't settle there and rot. When I say lightly I mean lightly. You do not want to make it stressed anymore or damage more flesh.

The brown does not come off with a baster. Nothing short of scrubbing with a toothbrush removes it.
