This is my first pond. Built a 4000 gal with savio skimmer and waterfall, 2.5 ft deep and a 5500 gph pump. I live in fl so the water doesn't get to cold. I purchased 75 small koi maybe 3in or so. Place them in the pond and they were doing fine. After about a week I started to find several dead in the morning. I had the water tested and the levels are all fine. It strange though because I only find them dead in the morning. The pond is fenced in so its not animals. Not really sure what else it could be. Any ideas or suggestions would be a big help.
Thanks
