Yikes, you vacuum your ponds, Bonnie? I barely manage to vacuum the house!
In 6 years we've lived here I have never vacuumed my pond, the water's nice and clear most of the time, and the fish are happy and healthy as long as the predators don't get them. Why do you do it?
There's certainly a mucky layer of dead leaves and stuff on the bottom, but any natural pond would have that. It doesn't seem to affect the water quality.
