    I have lost almost all of them now!

    Guess I will have to start over.

    How do I do it.

    Driain it, clean it and refill? Any products need to clean that would possibly kill the "bacteria" or whatever is going on?

    I don't want to go though this again.

    I had some huge fish given to me and they are all gone.

    Very sad to see them all go.

    Losing fish is never a pleasant experience.

    Not knowing exactly what caused the fish kill, the logical course of action would be to disinfect the entire pond.

    Completely drain and thoroughly clean the pond. Disinfect the pond, including all of the components- skimmer, pump, biofalls filter, entire interior surface and plumbing (as best you can) with a solution of common (5.25%) household bleach and water mixed at a rate of 1.00 - 1.25 oz bleach to 1 gallon of water. You will probably want to replace the filter media (lava rock, bioballs, etc.)
    Allow pond and components to completely dry for a week. At this time, it should be OK to refill and let it begin to cycle before adding fish. You can jump start the cycling by adding a cup of common household ammonia to the pond water. This will speed up the colonization of the beneficial bacteria.
    This should eliminate any pathogen that may be present in the pond at present, including virus.
    It appears that a disease was spread when you mixed fish from different sources.

    I have had the pond drained since Sunday. It is impossible to get all the water out. The last 5-10 gallon can I just pour bleach in it?

    Also I am going to spray the sides with the bleach. How long does it need to set before I refill it?

    A Wet/Dry shop vac will remove any remaining water.
    Refer to my previous post: "Allow pond and components to completely dry for a week".
