    Hi !

    Need some help with the following problem please:

    I have quite a few toadstool leather corals in my tank. From the beginning of December I noticed that two of my big leathers started shrinking in size (they were both about the size of a side plate) They still extended their polyps and I couldn't see any rotting or damage to the trunks. The one coral has now completely disappeared (I removed the last bit of the trunk - had no head on anymore) The other one that is still shrinking has shrunk to about 6cm in diameter (from about15cm). Some of the other leathers are also showing signs of shrinking.

    I do 25% water changes weekly, feed with Phyto and Zoo plankton every 3rd day.
    All the other corals, including LPS and SPS are fine.

    Please help.

    Are you using any phosphate remover?

    Hi Guys

    I only use carbon in the sump (4 bags that I change every 2nd month)
    I have been using Microbelift's Special Blend for the last 3 months, but at a much lower dose than stated on the packaging.

    off topic a bit but i would suggest you change the carbon every two weeks .. some will even suggest more often.

    im not sure if leather corals like a lot of flow, can you try putting it somewhere where there is less flow in the tank?

    I've actually moved the one leather that is shrinking from a medium to a higher flow rate area, but this didn't seem to have any effect.

    i don.t think they like the high flow areas.... they like lots of light and low flow IMO
    with high flow the tentacles will not extend and the coral will not feed and eventually die.... rather put it somewhere where there is very little flow

    Thanks

    I moved this specific leather to an area with similar flow to some of the other leathers that are doing fine ...for now !

    Is it advisable to maybe take the head on the leather that is shrinking, and fragging it ??

    I dont think its advisable foraging a coral that is not doing well IMO.. that will only stress it further and most likely kill it .. just let it be and make sure the water is clear .. pH is stable and the phosphates and nitrates are not too high

    Do you have any fish that might be feeding off it? I had this issue a while back, and I only noticed this fish doing his thing at night. so i swapped him out. It still took almost two weeks for the corals to lift up again.

    my views...
    carbon will last 30 days, run at 1ml-2ml per liter

    soft corals do like light, research each species for flow etc...

    what are your params? they do like nitrates and iodine, are you managing these? i dont think weekly waterchanges will cut it if they are large corals...

    Hi Guys
    Thanks for all the comments thus far. I have never added Iodine to any of my tanks i've had, I only dose calcium. How important is it to use Iodine? , and what make and dosage would you guys suggest?
    Thanks
