Hi everyone. Went out to my pond Sunday afternoon and all my fish were floating. I had 3 med size goldfish and a small koi. All my water levels were perfect and my fish were healthy and plenty of oxygen. The temp. In Louisiana has been in the high 90's for weeks. I believe the water got to hot as it was in full sun from morning till nite. Pond was only 300 gal and foot and a half deep. I have 3 in pipe at the bottom to swim in but I guess it was not enough. No shade and no plants. I don't even know if I want to try again...sick to my stomach.
