    New to Koi keeping and needing some help

    Hi... long time lurker and finally joined.

    I've been keeping 3 small koi in a holding tank for about a year now and finally upgraded to a 2000 gal pond with 8 koi. My ponds about a week old and everything seems to be running well. I've had the water tested and all levels are good.

    My problem is that my koi are flashing. They're eating, don't have clamped fins and are active but they still flash. I'm not sure if its because of rain, new water or parasites. I've raised my salt level (about 60 lbs of solar salt) and they're still flashing. Should I up my salt level again?

    Welcome to a True Koi Forum.

    Not sure what raising the salt level will do, and really don't understand why you put it in in the first place. I'd S&S the Koi and see what you find.

    Saying your water is good is meaningless. What is the temp, pH, ammonia, nitrite, and KH. Have you treated to neutralise the chlorine on filling up the pond?

    Hi Ace, like mentioned above you need to test all the parameters, these would be a minimum.

    A kit like this Amazon.com: API FRESHWATER MASTER TEST KIT: Pet Supplies

    along with this Amazon.com: API GH & KH TEST KIT: Pet Supplies

    would get you started.

    Without some KH as a buffer your pH ma be unstable from day to night.

    When I see flashing , especially if they are jumping I generally think of flukes first. You need to get a slime sample and have a look under a microscope. They are very easy to see as the heat from the microscope light makes them jump. It could be other parasites or a water quality problem as well.
