That is normally what I do, but the leak in my stream has gotten much worse.
I am now losing about 6-8 inches of water a week which is enough to put my
pump out of the water. When I said shut the VF down, what I really meant,
was moving the VF plants to the main pond, and then shutting down the VF so
I can clean it, and patch the stream. This way the plants are still there to
clean the water. I can circulate the main pond with a smaller pump.

Well why didn't you say so? ;o) I will agree to that. ~ jan
