    Have a 1,000 gallon fish pond and have had for 6 years with no problem. In last 2 weeks have lost 3 koi. I have treated the pond with a 7 day treatment of Knock Out. The pond water PH was high (9 i think) so I have put recommended stuff from a local pond store and it is down into range now. This am I have another fish floating on side and swimming with it's head down. I was told not to change water out it would stress the remaining Koi too much. Any suggestions on what could be wrong that I can correct. This is the first time we have ever had any problems with our pond. Also want to mention that my trouble started about 4 days after I found a live baby coon in our back yard, not sure if this would have anything to do with it.

    You need to test ammonia, nitrite, and KH also. If you can please post the results and some pictures of the fish.

    Hi, so sorry for your loss!
    How many fish did you have in there before they started dying? Could be that the fish load got to be too much for your filter to keep up with (?)

    I hope you can save the rest of your fish

    Trying to lower ph can cause stress and even death. A ph of 9 is fine for goldfish and koi. Best to leave it alone.

    I am so sorry about your fish. Test the nitrite . Are those lesions on the orange fish?

    How many fish and what sizes are they?
    When did you add the last fish?
    When did you do the last real bacterial treatment (prior to Knockout of which I'm very skeptical)?

    Wondering if raccoons could have injured those fish and they just died from wounds and shock? Although if the raccoons would have gotten a hold of them you would think they would have eaten at least one or more. Can the raccoons enter the pond by a shallow shelf or is your pond deep sided? If deep sided they might have tried to grab the fish and just injured them.

    If you have ammonia and nitrite showing up there is a water quality issue. Both are poisonous to fish.

    I recommend that you join koiphen.com and post to their emergency and health issues section. Post the symptoms and water test results in you request for emergency help as well as the treatment you already used.

    Make sure to test the nitrite and post that here and there. Ammonia should be zero and nitrite can be just as harmful, more possibly, and needs to be ruled out.

    I'd be guessing as much as you but here is a link with disease and symptoms that can help you narrow down the possibilities. Wait to start more treatments until an expert here or there can confirm the actual illness.

    Check the colour of the gills.
    Nitrite poisoning will show as brown coloured gills.

    What was the original reason for dosing Knock Out?
    What is filtration/water circulation/aeration?
    KH/GH numbers would be useful to know.

    You added a new fish to the pond and then the others started to die?

    I think she said the dying started two weeks ago and the fish was added a week after.
