    Hey guys,

    Took this shot yesterday, hasn't worsened today so from what I've read, isnt RTN but completely unsure. Everything else in the tank is fine, anyone know what would cause this?

    Not bleaching; that's STN. Many possible causes, and judging by the acro in the background, something is fundamentally off in your system for keeping SPS. Water parameters?

    Sorry to say, but that is not bleaching. That is tissue loss. You could try fragging whats left of the one frag, but the other one is dead.

    The other one is an anacropora, got it from reef pets - I sent gary photos of it and he said thats what they look like. Water parameters are the following:

    Ca - 470
    Alk - 9-10
    Mag - 1440
    Nitrates - 0
    Phosphate - 0

    On all of my other frags (I have around 40) I've seen 3-4mm of growth in the last 6 weeks, so I don't think it is a water quality issue or overall tank issue.

    Any other thoughts?
