    Calcium and alkalinity is a bit low, albeit not severely low. Have you checked for montipora eating nudibranchs? Have a look on the underside of the coral for the tiny creatures or their eggs.

    Butcherman,

    Ditto on what Viper has already mentioned.
    Also, do you have any other corals close to the Monti that could sting it ?

    I would perhaps suggest you correct the Alk and Ca to levels of 8-9 dKH and 450 ppm respectively. A waterchange of 20% or so wouldn't hurt either.

    Good luck

    The alk is a problem, the coral could prob handle the lower calcium. 7dkh IMO is pushing the limit.

    Checked underneath seems to be a brown spot underneath the coral maybe half the size of a ten cent piece

    1.025

    Pehaps something is eating it. Everything else is doing good.
    green birds nest and pink poccilapora doing well, as are mushrooms, zoas pinchusions.

    other live stock include 1 clown
    1 flag tail.
    1 lawnmower
    1 cleaner shrimp
    1 pepermint shrimp

    When I once had my alkalinity dip below 6dKH I saw tissue loss on some of my LPS as well. I would definitely fix that first.

    @viper357

    I think your right about the nudi brach. Seems to have been snacking on the monti
    and if a recall a few days ago i saw what was apparently a nudi which i dismissed for argonitelanding on the monti.... Stupid me :(


    I dipped the monti in iodine bath and gave it a little brush to try and clean it.

    quarintined it.

    What should my next steps be?

    My alk is 6.4 so that wouldn't be a problem. I have my money on Monti eating nudi's or low potassium. Mine all faded (Red and green) to a grey colour. One week of potassium and they are brighter than ever. Monti's are the first corals to suffer from low potassium and with the lack of potassium test kits they are what I generally use as a potassium deficiency indicator.

    The nudi's that eat monti's are really tiny. Hard to see without some form of magnification.

    After googleing these little bastards, they can grow up to 0.75cm.
    Apparently they can lay their eggs in every little crack and crevas of the monti.

    Hate to say it but dosent look good for my monti :(

    Try coralRx but to be honest you could buy a new monti for the price of that stuff.

    I dipped and quarinteened the monti, It seems to be on the mend :thumbup: but now my question. Once it has recovered how do i know its safe to put it back into the main tank?

    I would say once its starting to colour up and growing again.

    BTW, if you need to do a dip of CoralRX, I have some that you can use ;)

    Theres a big difference between 6.4 and 5. An alk of 5 really is too low- try raise it up to around 7 (nudis or not).

    Iodine also has a large part to play in the colouring up of green corals

    +1

    But if you are going to dose Iodine, please make sure you get a test kit for it as well - if you overdose , you may cause an algae bloom :(
