    No i don't think so all the fish in the tank are reef safe plus they in the tank now for 2 years. This problem only started i'll say a week ago.

    I'm no fundi with SPS, but some common causes of SPS suffering from Tissue Necrosis from the base up is things like swings in parameters, such as ph and temp, also a lack of trace elements can cause it. Do you add any trace elements, apart from water changes?

    Tissue loss from the base is usually due to low alkalinity or low flow. Maybe double check your alk reading with another test kit. I've also lost a few sps that showed the same signs but I found out it was my magnesium that is low.

    Any idea what your ph drops to at night? Are you running your sump on a reverse lighting cycle? That helps prevent too drastic a ph swing at night.

    I can't recall seeing a picture of your tank, but from the pics above it seems like an SPS dominated tank, you should really look into adding Trace Elements and also Amino Acids. A very stable dkh is also vital, when I tried a full blown SPS tank I remember reading that a dkh of between 7 and 8 was fine, but the day to day swing should be no more than 0.5dkh. You may need to consider investing in a Calcium Reactor if you have a high concentration of SPS in the tank, stability is the key here and if your daily consumption of alk and calcium is high then manual dosing could be really tough to keep up with, if you miss a day or two and your levels drop then it impacts negatively on the corals.

    Yes i run my light reverse cycle ph day 8.3 night 8.2 and i drip kalk 24/7 very slow to keep things stable no swings i checked kh at night and day 7.8 my Calcium stay on 420 and mag between 1400 to 1380. And yes i do dose amino's

    I tend to agree with Viper and Rory, I would watch the parameters.

    Have there been any sudden changes?

    Hi there like viper says it could be temp or ph,kh dropping to fast,you need to feed sps with a good planckton and if you do not have a chiller connected you in for big problems,what i will do is brake off the good sps to prevent further stn and examine closely for nudis and flatworm ,some times its very,very hard to see flat worm ,but the way your sps is eaten it could be nudi or flatworm ,check you temp on a hourly basis if there is a tem drop of more than 2-3 deg you will also have a problem,and a good plancton to use is kent in the small bottles,i think its called plancto or so,good luck

    I would frag 2 or 3 pieces. I have also lost some SPS when all parameters appear stable. Stability of Alkalinty is of utmost importance. IMO, the RTN/STN can occur some time after unstable parameters. These are just the symptoms we see well after the damage was done.

    Is that hair algae on the back glass?

    First thing I would look at is stability.... More important than parameters. I would frag them and move frags to another system.

    Hello Charl,
    Eish man these things are hard to pin point...been down this road all too often myself.

    Forgive me if asked already,

    What is your total water volume?
    How often do u water changes, and % of above water volume?
    List all the elements u r dosing, and how u doing, frequency?...e'g. alk u doing daily using sodium bicarb, etc
    Exactly how often do you test/frequency your alk parameter, using what test kit?
    You mentioned u use seachem...nothing wrong that, i use it too.
    How many SPS pieces do u have in total? and how many of the said total are showing these symptoms?
    Do u know (accurate?) how much Ca, Alk & Mg your system uses in a 24hr period?
    The "whitening" where is it more concentrated...tips, stem or base?
    I see u have a plating/s monti's are these all OK?
    Have u added any new LR recently to your display?
