    Hi,

    Please help me if you can. I have coralline algae, which I do want in my tank, growing on 2 new small zoo colonies that aren't opening, which I don't want. All of my other corals are not experiencing this. I have 3 other small zoo colonies that I got at the same time, that are a different color, orange that open fine and they are free from this menace.

    Would a Medi-coral dip help?



    Ammonia and Nitrite= 0
    Nitrate= 20-40 GRRRR!!!!!
    PH= 8.2
    KH= 11-12
    Calcium= 420
    Salinity= 1.023-1.024

    Sorry I don't have a phosphate reading, I don't have a kit to test it yet.

    Thanks for the help,

    Jim

    To my knowledge, coraline doesn't grow on live tissue. Either the coral is dead or it's not coraline. It could be cynobacteria. Do you have a pic?

    My immediate thought was Cyano as well, I also think GM nailed this one. Coralline can not grow on live tissue.

    Given that your nitrates are elevated this would point towards a nuisance algae or in this case a bacteria….cyano.

    Get a turkey-baster and attempt to blow it off and up date us. If it comes off….cyano is more than likely the culprit.

    If you do not have a skimmer you probably should, test for phosphates and begin water changes to get the nitrates down.
