new to the forum here guys. I am in dire need of help here with a clients pond I built about a month ago. The pond is about 14 ft long by 4ft wide and is in the shape of a bone. Is about 2.5 foot deep. Has a 3100 gal pump with a waterfall at each end with a 2ft drop to the pond. and a pond skimmer. Have an aerator in it as well. I have drained the pond probably 5 times and added beneficial bacteria, and water conditioner every time. I’ve been using wild blue gill as tester fish and those are some of the hardiest fish I can think of to use with no success. The only thing I can think of is the water temperature being too high considering we live in Texas but half of the pond has shade and the other half has lilies so I’ve made every effort I can to cool this pond down. I’m about ready to try using RO water.... any ideas guys ?
