What is this red/purple-ish color on goni's skeleton?

[Blake423]

Hi all,

My goni was dying probably due to a faulty bottle of Phytoplankton.
I believe I have already stop the dying and it is growing again.
But I just notice the edge of the skeleton are turning red/purple-ish. Photo attached below, it was taken this morning so the polyp are retracted, they will be fully extended later .
Are those bacteria infection? Why it turn red/purple-ish?

My parameters(salifert):
Phosphate: colorless
Nitrate: very very light color
ALK: 8.6
CAL: 410
MAG: 1350

Thanks

Could be cyano. Does it come off with a gentle blow of the turkey baster?

No, it is not cyano, it doesn't come off. It just like the skeleton is dyed with that color.

got the same thing on one part of one of my gonis, how did it go with yours ?

Do you have other gonis? If so how are they reacting?

Alive and extending, except for the dead skeleton, generally are quite good. Some edge shows sign of growth over the dead skeleton.
Still not sure why purple, but it seems it doesn't bother the coral.

I have a alveopora, it's quite good and growing.
