    Ok,
    I'm not sure how serious this is, but I'd rather start the thread here and get an answer ASAP.

    My Colts/kenia (I have 4 of them) trees are not opening - this is going on for two weeks now.
    The same with my sarcophyton is not opening.
    I know that they do sulk, but for this long? Not so sure....
    Every now and again I'll note that two of the 4 will open SLIGHTLY, just to close again.
    And sometimes I do note the slime mucus on them - so it looks like something is bothering them.

    I've changed the flow on them (first a bit more, then a bit less), increased light period - but so far nothing worked.
    I've even moved it to new locations...

    This morning when I've cleanded my algea scrubber I've noted that the screws that I've used to bolt my fans on to the algea box were rusted (I did put some sylicone on, but obviously not enough). It looks like some of this rust is dripping into the tank. I'm not sure how much did dripped into the tank. (and for how long)

    Now -
    1. can one test for rust in the tank?
    2. Why is all my other inmates happy (candy cane, galaxy, zoa's, nemmies, fish, snail) All are feeding and doesn't look stressed.
    3. If it is indeed the rust - how long will the effects be in the tank? (I must do a water change obviously)

    The rest of the water parameters:
    Kh - 8
    Ca - 370
    salt - 1.023
    Nitrates - 0
    Ph - 8.4
    Temperature - 26.5 - 27 degrees

    I doubt that rust would cause it. Is it metal screws. If its metal then it would have the same effect as gfo. If other metal then it might cause some reaction. In a softy tank i would prever a bit of nitrate, say maximum of 5. Add new carbon and keep an eye on the corals

    I'm no expert, but I had the same thing happen... colt wouldn't open at all for several weeks. Then I noticed the 'stalk' of the coral was dividing. After division completed the branches started opening up again. Same with my sarcophyton; closes for a while (days) and sheds a layer... opens back up and is fine. I think this is normal growth cycle.

    I woulden't worry about the rust.

    Double check your salinity with another method. You might find its actually lower than you are reading now.

    cool.

    I'll double check the salinity...
    Hope that you're right.

    But why is none of the LPS and Zoa'z affected?

    Raven - perhaps try and add some commercial iodine / iodide at first. Soft-corals respond positively to iodine dosing.....

    do you perhaps have another tank? If these softcorals stay closed even longer, I would rather suggest placing them in another tank with some semi-decent lighting, (even if you don't have filtration on this tank - you can still just do water changes, with newly mixed water)......

    The problem is - there is indeed a point of no-return. (Unfortunately, I cannot tell you EXACTLY what this is).... once the corals go past this point they might just die......

    Do at least 2 to 3 water changes in your tank - just to be on the safe side........ And if the corals still don't show ANY improvement - remove them and place then in a "seperate holding tank", until they are much better.

    Are you using the vodka and zeolite method cos mine sulked for 3 weeks when i started dosing - i actually found that the brightwell bio-fuel was too strong and when i stopped dosing and reverted to vodka the started opening up again. How are ur magnesium levels?

    I've started to dose iodine last week and monday - no improvements yet.
    I've started dosing this as mudshark mentioned that the ATS might remove iodine from once tank.
    Unfortunately I don't have a spare tank...
    I will be able to do a water change only Tuesday/Wednesday (need to build up water supply from RO).
    But I will make sure that I can do at least 2-3 water changes this week.
    There are times that the corals looks a bit better, just to shrink back again!


    Nope - I don't dose vodka.
    Magnesium - not sure...:( I normally don't test for this.

    I only dose:
    1. backing soda
    2. gebluste kalk (lime)
    3. Iodine (only from last week)

    Can this be a chemical war thing going on?

    The coral list:
    Corals:
    1. Galaxy (x1) -- Normal
    2. Shrooms (x 20-30) -- Normal
    3. Colts (x4) -- Sulk (all 4)
    4. cabage coral (x1) -- Normal
    5. Candy cane (x5) -- Normal - opens every night and when feeding
    6. Zoa's (x4-5 colonies) -- Normal
    7. euphyllia (x3) -- Normal (maybe can do a bit better, but I think my flow is a bit much for them at this stage...)
    8. sarcophyton (x1) -- Sulk
    9. Nemmies (x2) -- Normal
    10. unknown soft coral (x1) -- Normal - Will take a pic of this one - can't remember the name... :(

    This statement might have something to do with it??
    Remember most marine life can adjust slowly to a variation of different perameters (might not colour up or flourish 100%) BUTstability is one of the most important issues in an aquarium.

    The rust IMO shouldn't be an issue if a small amount enters the water.

    It might...

    But I'm not 100% convinced - why is the rest of the corals doing ok?

    Got home this afternoon - and still it's all closed...:(
    I'm really going to cry soon...:(:(:(:(:(:(:(:(

    What other water parameters can/must I check?
    Must I add more food?

    I can't think of anything that I've changed - besides the fact that I've added the two extra sumps with the extra DSB....
    The sand that I've used is from my frag setup's DSB...(I've washed it before adding it to my tank)

    I'm getting water ready for a water change - should be able to do water change Wednesday.

    PLEASE HELP!!!!!!!!!!
    I don't know what to do anymore...

    Eish Raven, Hope you find a solution!
    Think that is the most frustrating thing .. If you do not know what is going on...

    Good luck.

    Hi,
    2 days ago:

    The rest of the water parameters:
    Kh - 8
    Ca - 370
    salt - 1.023
    Nitrates - 0
    Ph - 8.4
    Temperature - 26.5 - 27 degrees

    I'll take measurements again tonight.
    What parameters are you looking for?
    I'll have to take the water to the Vis Dam to be tested for some of the parameters as some of the test kits are a bit old....
