I have new 2000g pond and added declorinator and Micro Lift PL and added four 8" koi a week ago. My ammonia is 0.25 no nitrites or nitrates yet. All the fish seemed fine but then this morning one of the koi starting swimming around on the top of the water with his back sticking out of the water sometimes. This evening he died. All of the other fish seem fine.
Does this swimming at the top of the water and then dieing that same day have a diagnosis that I should treat for the other fish?
I have not added salt to the water. Should I?
Thanks,
Dwayne
