Thread: Koi Death.

  1. #1

    Koi Death.

    Good afternoon people,I have a 1500gallon pond with only 3 koi in,easypod,UV and 75 litre air pump.Decided to add new additions and bought from reputable dealer,and koi enthusiast.All was well,eating, swimming,no signs of stress or problems.. overnight one died, gutted but sometimes that's life but now lost another then an older shubunkin,full adult.
    Regular water changes,PH 7.4, amonia minimal..I am baffled and don't want to lose anymore but don't want to treat without knowing what the issue is.
    No physical damage and nothing to go on..
    Your thoughts and help much appreciated.
    P.

    Sometimes the stress of moving fish brings on parasitic problems,mainly whitespot,but they should show symptoms

    Swimming fine,look great then find a corpse..the shubunkin had been in there since I built pond,that must be over 12 years.
    All the big boys are fine.

    Hi,apologies for not answering as quickly as I should..water temp was 25 plus,so I have installed a sail over pond as a precaution,thinking heat may have a bearing on matters,no more losses thank goodness and are all happily chasing watermelon around,now to answer you John,Nitrites..zero,I tested tap water at same time to see if there was a different reading,,PH 7.6,Amonia 0.25.They are not stressing today or any other to be fair.
    Tests done with new API kit.
    Thanks for your patience.

    Are you dechlorinating the tap water ok?
    Is there enough oxygen going in there.?
    Have you a pic of your set up?
    John

    Yes dechlorination of tap water,use Chemical Factory Thilosophate,75 litre air pump running 4 stones.
    Noticed one had a milky eye so have used Acriflavine,UV off if course,on a brighter note after sail put up they are happy as Larry.
    Cheers
