blair5002 that's some ice hole sculpture you got there, you must have a good size air pump, either that or your putting bubble bath into the hole.

Scruffy I'm pumping water from the stream above the waterfall when I'm at the pond and only if it's above 15 degrees. The pond is staying within 8 inches of full.
