    Hope someone can help.

    A couple of days ago I noticed some of the edges of this coral turning white. It seems to spread slowly. I don't know the name of this coral, maybe someone can help here too....

    Thanks!

    No, there is no skeleton, straight on the rock. I have another pic, but not sure it's any better. Thanks

    what corals are near it? being a soft coral, there are a few things it can be so we need to narrow down:
    how long have you had it?
    what coral near it?
    what are your no3 levels? alk?

    Hi @dallasg

    I bought the tank second hand from someone with all the livestock - it's been running for about 3 years. The only other coral close to it is a zoa and star polyp. None of these are touching the coral.

    I will have the water tested today and let you know about the readings.

    Thanks.

    cool, from my experience, only time softies went like that was from stings from another coral, no other side effects and coral is still healthy.
    also with soft corals they dont like sterile water, ULNS, so lets go from there

    Thanks, I do my RO topup straight into DT as I no sump - do you think perhaps the RO caused this?
    Will it heal itself or do I need to treat it? Thanks!

    i dont think from RO, but try from the other side and add it slower and lets see.
    no just leave if for now and give it a day or 2
