    How long have you had it.
    They tend to grow like weeds.

    i bought some - broke the rock with hammer and screwdriver - placed one piece in high flow high light area and other in low flow, low light area - mine are fine - just that the one in high light and flow opens first/faster in the mornings

    Hi Warr - just something about "soft corals":
    Generally, they sometimes tend to look like they are "sulking" (withdrawn, shrunken, ugly looking). This happens every so often, and a lot of times does not have anything to do with ANYTHING.

    The coral polyps are perhaps "digesting" particulate food, and do not require light at this stage for energy, or perhaps it is preparing to excrement food wastes...

    Give it a day or two, and if the coral stays closed like this for more than e.g. 2 days - then you should perhaps think of checking water parameters again, water temperature, etc, etc...

    Usually star polyps are extremenly hardy. So - perhaps give it a bit of time. Monitor the situation.

    Exactly, if water parameters were not good, i thought the Hammer or Heliofungia would be unhappy first.

    Will monitor, also maybe there is too much light, It is situation 300-400mm away from a halide.

    Hi Warr - that's cool! 300mm to 400mm is 100% perfect!

    Well - perhaps it's some toxins in the water that might be irritating it. Are you running activated carbon?

    No purigen.

    If there were toxins wouldn't effect my pincushions ?

    Leather corals, and star polyps would be affected differently by different toxins. Leather corals can excrete toxins that affects star polyps, but not LPS - I don't know the exact dynamics of toxins, but I do know that it could be specific to a type of "competitor"....

    I am not sure if purigen would remove toxins - does it say so on the bottle? I know about ammonia/nitrates, but not sure about toxins...

    I have no idea either:

    This is what it says:

    Purigen™ is a premium synthetic adsorbent that is unlike any other filtration product. It is not a mixture of ion exchangers or adsorbents, but a unique macro-porous synthetic polymer that removes soluble and insoluble impurities from water at a rate and capacity that exceeds all others by over 500%. Purigen™ controls ammonia, nitrites and nitrates by removing nitrogenous organic waste that would otherwise release these harmful compounds. Purigen’s™ impact on trace elements is minimal. It significantly raises redox. It polishes water to unparalleled clarity. Purigen™ darkens progressively as it exhausts, and is easily renewed by treating with bleach. Purigen™ is designed for both marine and freshwater use. This product is sold by volume. Cited weight is minimal weight.

    Perhaps someone who knows Purigen VERY well can assist here?

    In the interim - do you have some activated carbon somewhere at hand? If so, perhaps add some temporarily this afternoon/evening to the tank, and see if this makes a difference to the star-polyps?

    Best guy to chat to about Purigen is ObiWan.

    However I would always run carbon as well. Warr when is the last time you recharged the Purigen?

    I have no PO4 detected on my tests, but it may still be in the system, it is being consumed by cyano or algae and keeping the levels low.
