    Hey guys and gals - need you help with a mystery. Came home last night to at least 10 of my 20 + nerites in the big tank lying dead on the open sand. I can only assume there are others in the plants.

    Ammonia and nitrites all at zero, nitrate totally acceptable, CO2 is normal, fish seem unaffected, pH was 6.8 which is normal for the end of the day... I am stumped!

    The only change I can think of is that I decided to try dry dosing my ferts instead of making a solution... maybe I overdosed by accident? Too much copper in the Micro’s or something?

    Any ideas?

    My index for suspicion of the dry ferts is pretty high given the information provided. Sudden death like that makes me think toxin, poison, etc.

    What did you dose, how much, etc.

    Also, have you confirmed that they are actually dead dead? Theres a minor possibility that they closed off because they are stressed and might still be alive.

    Regards,
    Ed

    Thanks, Ed. Yes, I confirmed they were dead- flaps were open and loose.

    I am using the rotalabutterfly calculator, dosing KNO3, KH2PO4, and CSM+B, all from Green Leaf Aquarium. I don’t have the exact amounts handy, but I measured carefully according to the calculator- I even allowed for the fact that my 135g only carries about 105g of water.
