    Yup it is called RTN or STN. It looks like cyanobacteria on it?

    What lighting do you have, tank size, water params.

    Hysterix LOVES light

    I would frag the healthy bits IMO

    Hi Warr - that "purple stuff" on the Hysterix - is it hard? Or does it feel slimy? Perhaps it is some form of cyano even, and not corralline algae. I do not know of any corralline that will start to grow on a "reasonably healthy" SPS coral - only on the dead SPS skeletons corralline would grow...

    Hard, so it's dead. Can I leave a coral skeleton in the tank or must it be disposed

    Remember this unit has two powerheads pumping 4500l/h, no cyano going handle this type of flow.

    This is RTN /STN will it attack my other corals or livestock ?

    As someone mentioned RTN i would frag the good bits, near the top, then dispose of the rest

    How long did it take to get to this stage Warren? If it has taken a while (a few days) then I don't think it is RTN. Move the coral into slightly less flow for now, see if it will recover a bit.

    Can you see any polyp extension anywhere on the coral?

    Agree with cyanobacteria. Phoromidium: Dark red encrusting gelantinous growths.

    This is the problem, too much linear flow. Try to get random flow and do not point the PH directly at the coral as you can shear the polyps off the skeleton.
