    From past experience, where the algue grows, the coral dies, I'm not sure how to remove or treat it, but lost many sps variants due to algue in the past, high nutrient levels is normally the cause of the algue getting out of hand. Frequent water changes might be a suggestion and shorter lights burning duration.
    Kind regards

    Thank you, and not good, :( , i checked by nutrients and they are all fine. Apparently you can brush it off but it is not going to be easy to get to all of it...

    I tried removing it using a soft toothbrush, but it still died at the end.
    All the best

    That looks more like the hairy type to me, won't just blow off, if it's the purple(cyano) type, it better to suck it of and remove it completely from the system as it holds nitrates, if it is blown off, the nitrates are released back into the system, that's what the fundies recon.

    The toothbush will hurt the sps tissue. Imagine me taking a bath with a steel wire brush and scrubbing as hard as i can.

    No thanks, don't even want to try imagine you in the bath, needless to say, that's why it died in the end

    Thank you for the link. I have tried blowing it off but that stuff is like steel wool stuck on it with superglue :eek:

    I think you are right, I have removed most of the dead parts I can easily get to already, but there are a big part right at its centre. I also cut down on the lighting, think it was a bit strong.

    I have about 53x flow at the moment.

    Prune the tips to remove red algae as those tips are dead and increase waterflow

    flow is not just about numbers. direction and speed is also important, judging from the pulsing xenia and the clown hosting in it nest to your birds nest, your flow needs to be looked at

    Almost zero, would say about 0.2 ppm,

    The rest of the parameters in case:

    Phosphates ~ 0
    Nitrite ~ 0
    Ammonia < 0.25 (salifert test the water is a little milky)
    Ph ~8.1
    Ca ~ 430
    Alk ~ 8.4
    Mg ~ 1340
    Salinity ~ 1.026
    Temperature 25+-0.5

    Some will disagree with me but imo there is carbon being left in your system after all nitrates and phos used up. I would reduce the amount of cubes

    That is a very interesting idea. What would the effect be if there are excess carbon in the system?

    Yes it would result in cyano bacteria.
