Thanks Guys.Jeff,I can see where the rocks would be a lot of trouble.The larger ones would probably be getting stuck between the pads and I would think it might cause uneven pressure.But I'm no pro that's for sure.lol!From the pictures you've posted,I would say my dirt is around as rocky as yours,maybe a little more or less.If my pond looks anywhere near as good as yours,I'll be more than happy!
