Well no buzzards or egrets around the pond this morning! I picked up the dead ones yesterday afternooon and didnt have any this morning. I have a 2.5" pvc pipe ran from a spare well I use to put water in during long dry spells. I put an extra 10' on it so the end would hang down into the water a few feet. It just gravity feeds from well with no pressure,( tank by passsed.) I drilled a hole in the top of the pipe close to the well so it would suck air in and mix on the way down. worked great,! Water was bubbling and churning like a small out board was running. Thanks for the help guys.
