The pond is still down, about half pool. The aeration was going 24/7 until we had an above freezing day last week when the moisture must have gotten into the line and caused the freeze up.

Got it flowing again today with the rain and maybe the raise in the pool allowed the hose to come out of the surface ice? When I left it was bubbling through off and on.

The bubbler is in the deepest part of the pond, now about 4-5 feet of depth. I've been reading about super chilling the water in the deep areas is not good for the fish. At this point in time I have no choice but to leave it where it is, and wait until spring to see if the trout make it.

I have some concern about putting anti freeze in the line with trout in the water, so I hope it dosen't freeze up again.
