New Koi POnd
So this is my 1st posting about a newly dug pond. My pond is 2300 to 2500 gallons, 13'x8' with the depth of 47 inches, and lined with billboard tarp. I have hooked my homemade skippy's bio filter to a 1800gph submersible pump.
I have treated my water with water dechlorinator and bio starter.
After 3 days of running the filter, I introduced plants and 50 feeder fish. The next morning 10 to 15 fish were dead and the rest to this date (4 days) are resting at the bottom of the pond. I have checked my PH which is 7.6-7.7.
Does the above raise red flags? is there something going wrong in my pond or I just have to wait till the pond cycles?
Current water temperature is 56F Thanks,
