    Hi all,

    I've been a bit quiet on here recently, mainly because things were going well, until I came home from work tonight...

    Devastated. All my fish are dead. :( It seems a sea cucumber (which I didn't realise was even still in the tank and alive) has crawled into a powerhead and poisoned the tank.

    The inverts (crabs, snails, shrimp, urchin and clam) seem OK so far, though a couple of my montipora have lost a bit of colour; now looking a bit grey.

    I've pulled out the following fish:
    • Sailfin Tang
    • Yellow Tang
    • Kole Tang
    • Dwarf Angel
    • Clarkii Clown
    • Azure Demoiselle
    • Cortez Rainbow Wrasse
    • Mandarin

    I can't find:
    • Flame Hawkfish
    • Green Chromis
    • Randall's Goby

    I'm guessing my crabs will have to clean up the last three.

    What do I do now? I presume a lot of water changes, but how do I know when the toxins are at a low enough level to reintroduce new fish? I can't drain it completely as I've got corals in there and don't think I can't lift the rocks out as most are epoxied together.

    Clearly I don't want to leave it without fish for too long, or my bacteria will die off and I may suffer new tank syndrome.

    Cheers,
    Ade

    Thanks Jim. My own fault for not protecting the powerhead and not doing enough research when I bought it (and trusting the LFS when they said that even if it died, it shouldn't be able to take out a 400+L tank). From reading into it further this evening , it seems my type (Sea Apple) are particularly toxic.

    A bit of Googling suggests water changes, lots of carbon and skimming, so I've used up all my carbon in two net bags and suspended each in front of a power head. 70L of RO filtering tonight, ready for a water change tomorrow.

    Then I'll speak to a (different) LFS tomorrow and make them happy over the next few weeks, restocking.

    Trying to look on the bright side, I can now start to stock in a more planned manner, and avoid bullies like my Clarkii clown, which has victimised a number of fish over the years...

    yeah i had one years ago
    beautiful creatures, but never again
    yeah start with the softest and leave any potential risks till last

    when buying fish i now watch a fish in the LFS tank
    but leave it till the following week to ensure its feeding well etc
