So I have a situation that's never happened to me before -- the temps have been so cold that the waterfall has formed a nearly complete shell of ice. There is one little sliver, about 1" x 8" that is open, and I'm pretty sure that will close up tonight. This will be the first time I've ever seen the pond completely encased in ice, despite the fact that the water is still flowing.
I would assume that if the pond is completely enclosed, this means no oxygen is getting into the water, even though the water is still flowing through the filters and splashing down the falls? I'm not too worried about it, since our temps are supposed to shoot back up above freezing tomorrow (which here means that everything will melt FAST), but I'm hoping to get a picture of the falls in the morning.
