fnc, when the pond was built, a lot of post oaks were cleared. I had them pushed to the bottom which was about 17 ft deep. We got a 2 inch rain and the water turned inky. After another rain, I stocked BG, fatheads and cats. They all died in an hour.

I bought enough chlorine to kill everything in an olympic sized pool. It was still lethal. I had to pump it all dry and let the summer sun dry everything.

I cut a fresh oak limb and put it in a bucket with the pond water as a test. It turned black and I learned my lesson. Lusk tells me that not all water will be affected; depending on the chemical makeup of the water. In my area, I'll never do it again. Your mileage might vary.

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.
