    Hi All,

    I have had this staghorn for a few weeks now and have noticed that the tips of some of the branches are whitish while the rest of the coral is a dark purple/blue.

    The coral continues to grow but was wondering if this could be bleaching and if so, what can be done about it

    Its difficult to see from the pictures whether the white is growth tips or receded tissue. But my guess would be bleached tips by looking at the second pic.
    Could be a function of parameters or excessive light or the onset of something more sinister like stn.
    Try and take a more focussed picture. Have had tissue recession before with the suspect being elevated Ca and Mg.

    Is that GHA in the background?

    There is some longish hair algae that the CUC do not seem to eat .... mostly (I think) because there is plenty of shorter algae to eat .... on the back pane ... the snails (27) are cleaning that away quite quickly

    Definitely looks like a caulerpa species, most likely C. taxiflora. Could also be Caulerpa C. sertularioides or C. ashmeadii I would not advocate most Caulerpa species to be kept in aquaria, or refugiums for that matter. However, do not remove it by trying to pull it off the rock. Especially if C. taxiflora, as it is highly effective at spreading to plague proportions from the smallest piece of Rhizome (stalk).

    Please read the bottom part of my lengthy post in this recent thread for justification of the above: http://www.marineaquariumsa.com/bio...ation/52635-leng-ecosystems-2.html#post841429

    I would suggest removing the rock it is on and blasting the area with one of those hand-held butane torches used by plumbers or chefs for flambéing a crème brulle.

    Not really an option for me because I made a pretty big structure by cementing most of my rock together, so it would basically mean tearing my tank apart.

    I only have 2-3 little branches so I will bide my time and see what happens for now ... if it starts to get ugly I will have to resort to more desperate measures

    Thanks for the advise

    If there are only two or three small pieces I would take some putty and cover it so that it does not spread.

    This might sound funny but do you run LED's? If so is the stag new to the tank?

    Did the tank where the stag came from run LED's? You might be burning the sps with your light's intensity. Move it lower down and assess your light settings.

    When looking at the pic of the stag it seems that the tissue facing the light is bleaching as well. Please take a closer and clear pic if you can.

    Definitely bleaching from too intense light from led's. When introducing new corals to a tank illuminated by leds you really need to take your time acclimating them. I personally acclimate mine ove 2 - 3 weeks moving them up slowly. I leave any new frags or corals on sand bed for 1st week then start moving them up slowly.

    Cant agree more. Remember the general intensity that LED's run at is rather strong.

    Another cause of burnt SPS tips is high Alk in a low nutrient system. Alk swings is another cause.
    Whats your Alk sitting at bud? And how are you dosing Alk (manually,doser, Carx)?

    My ALK is sitting at 7.3 at the moment and I do manual dosing usinf Bicarbonate of Soda. There has been some fluctations recently (down to 6.4 last week from a high of about 8 from the week before - is that large?). I also noticed that my Mg is low (1160 vs recommended 1380 from Red Sea) so I am raising this now too.

    - Could low Mg also cause this burning ?
    - Will this frag ever recover or will this set in as a type of "rot" and just get worse ?

    It is a bit more of a swing than what I would call ideal..

    That swing is big enough for me.
    Had the same problem and lost a colony or 2 from that swing.

    Your tank conditions is basicly the same is mine.
    Strugling to get my mg from 1150 to 1300 and my alk is permentantly on 7 for the past 2 months.

    How much do you topup each week and what is your topup water's alk?
