Oh dear. I am no help because I don't have a pond.....YET.....but I sure want one!! One day, maybe, I'll have a pond.

Hope you get it figured out. I am a member of a Pond Group on MSN. Maybe someone there could help you. Here is a link:

Obviously, you will have to join to be able to participate, but maybe you can get some answers there.

Good luck!
