    is there something wrong?

    I have had my pond for a year now. Its about 900 gallons. I run a pressurized bio filter with uv and my water is always crystal clear unless my uv bulb gets weak. Anyways last summer i had my koi feeding out of my hands and my sons and wifes also. I put some algecide in last summer and killed all my goldfish and made my koi all very sick. I only lost one. 2 or 3 jumped out and were out of the pond for who knows how long. Well, since then they have not been the same. They swim around normal when im far away and havent been seen, but the seem to dart a tad every so often when im standing by the pond are they sick or is this behavior normal. Here is a video.

    ammonia was the lowest reading on my pond test kit i cant remember the actual ppm.
    ph 7.0
    hardess off the chart high
    and 0 nitrate
    0 nitrite

    so, are they just afraid of me still, or does something look wrong.



    them swimming but keeping to the other side of the pond

    Give them some time, your last video says that the koi are finally eating from your hand. It might take them the same ammount of time to associate you with food again.

    Whenever I see 0 nitrate, I get concerned. Unless you have a flow-through fresh water system, the nitrifiers should be producing some nitrate. So, I'm not sure your readings are reliable. Ammonia in the water can make koi skittish.

    My guess, there is something wrong with food or they associate you with pain.

    That is a very small pond for koi so there is little place to hide from a preditor and what you describe is probably what happened. I would suggest that you put a few pices of culvet in for the fish to hide in.

    I will try it I have been thinking about putting some more hiding places for them in there. Hopefully it does the trick.

    Lets just go with your one sentence. My fish are ok when they do not see me. This makes me want to lean towards the fact that your pond environment is stable and your food is ok, maybe. Do you have children that run around in the back yard. Do you have any animals in the back yard,pets or wild ones. Is their something that creates a darting or fast motion towards or around your pond. Your fish are darting at the other end of the pond away from you. Do they dart by you?When my fish get spooked they well dart for several days before settling down. They show the same signs as yours does. I'm just a beginner, take it for what it's worth.
