    Over the last few days my plating monti has started going white from almost the centre, it seems to be spreading. I have been seeing good growth on this monti and it's frag for the last couple of months so not sure what has gone wrong.

    It hasn't happened to any of my frags so I don't think it is related to parameters but here they are in any case:

    Ca 450
    Mg 1480
    Kh 10.1
    Sg 1.024

    Over the last 6 weeks the only major changes have been new lighting, changed from a T5/Led combo to just LED, swapped my Seio Wave Maker for a Jebao WP40 and changed my return for a DC Waveline.

    What could have caused this? Should I leave it to see if it stops spreading or remove the white pieces to stop the spreading?

    Sorry for the bad pic's, was in a rush this morning.

    LED lights may be a bit powerful.

    I don't own SPS Corals, but could it be that the sudden increase in Lights caused Light Shock..? Don't a person have to also gradually intensify Led's..? even for SPS...?

    Looks like you might have monti eating Nudi's

    Bleaching from the bottom is usually an alk or temp swing.
    Have you checked for any predators?

    Check to see if the monti has any polyp extention. The bottom 2 look unaffected.

    The bottom two are separate frags that aren't affected at all.

    I haven't seen any predators. I recently added a birds nest that is fairly close to the monti, could that be an issue?

    My new lighting is actually dimmer than my previous setup of 72W LED's + 216W T5's. I now have 142W LED's. Here's the comparison of the two, I think I was running a little too much with my previous setup.

    When my tank cracked my some of my monti were placed inside my sump with some LED light very dull.it also became white.Placed it back in the tank under MH and a few days colour started coming back.

    I think the light is your problem.

    I hope not :( the new light wasn't exactly cheap. Any reason why the frags that are much lower and receiving less light would not be doing the same?

    If it was light shock the whole coral would lose colour. Yours does not look like bleaching, its more tissue loss if its that white so quickly.

    Looks like some sort of predation or stress related from parameter shifts.

    I do think LED burn would be across the whole coral in this instance

    Doesn't look like bleaching to me. Going with butcherman here and saying a grazer of some sort.

    Right now I am open to any advice, will try a dip and see if there is any improvement. If it carrys on after a few dips I will try adding some more light and see if that helps. It does look more like flesh disappearing than bleaching though.

    if it nudis and the nudis have eaten the polyps. There is not much you can do to save the coral. If there are area's with polyp extention. Tou xan try frag the healthy sections. But the nudis are still in the system. Once there are no more montis. The nudis will die off. I had to go about 3 months befor reintroduction of montis to my tank.
