My pond doesn’t need much attention in winter since it freezes over and the fish just lie on the bottom in a state of hibernation. All I need to do is to make sure there is a bit of open water so that there is some oxygen exchange. When I first built the pond, I made a deicer (pictured here) that uses two 25 watt bulbs to generate enough heat to keep ice from forming underneath it. That’s enough to keep the oxygen in the pond from being depleted.
It has worked well except last year when one bulb burned out during a bitter cold spell and the remaining bulb didn’t create enough heat to keep the water from freezing over. By the time I discovered it my best fish had died (of, course!). So the chore I did last Friday was to melt the ice around the deicer so that I could get it out of the ice and replace the bulbs. I can’t chip away the ice because blows to the ice can actually kill the fish. The change in pressure caused by beating on the ice can rupture their eardrums (yes, fish have eardrums) and that can kill them. So I had to use hot water to melt enough ice to free the deicer. It took me about 2 hours.
I know that sounds like work and it was, but I only need to do it once during the winter. I got it accomplished yesterday and the new bulbs should last the rest of the winter. I am happy and I trust that my fish are, too.
