    Hey guys,

    My tank has been very stable and all other corals look healthy. However, this specific coral is not doing so well and I only noticed this a few days ago. It has been growing fast but not it looks like RTn or STN. could be something else but what do you think?

    I have a 75 gallon and I use Kalk for top off. My params are nitrate 0 Phosphate 0 calcium 450 and alk of 10. I dont have a mag kit but do you think that could be efftecting it? Here is a picture

    Looks like STN to me. What kind of flow do you have in there? That particular coral loves flow.

    Mg might be causing an issue, but your calcium is at 450, so I doubt it.

    It is a dry heat, yeah right !
    Nothing is stinging it? Like some LPS, majano.......?

    It has good color and PE. The things that have caused STN and RTN for me have been

    Alkalinity swings
    Flow issues
    Placement of coral with relation to dosing and ATO.
    Temp swings

    If worst come to worst consider moving it and or fragging it.

    Good luck.
