Bob; I also hit sand when my pond was dug, its about the same size as yours. It also looses about one inch a day.The well I put in cost me about 3000 with the extra elect I had to run, it pumps about 15gpm it doesent sound like much, but I start it when the pond gets about 6 inches low takes two days to fill back up.so I run the well two days a week, no problem I;m glad I did it...jimmy
