My pond is in full sun, at least until late afternoon, since it's about 25' behind my house, on the east side. No large trees to shade it at all ....yet. I've planted small sized trees to the east of it, but they are Burgandy Red Buds and those do not get very tall, so I still should be in pretty much full sun.
I know the cost of the heater will be high, so planning to not run it until the temps are below freezing, and still keep the fountain going, just to move water. The stream and waterfall can be unhooked extremely easily, just a matter of loosening 2 screws and removing the line. The line runs the outside edge of my stream, so it will drain properly. Then I'll drain the DIY skippy filter and cover it so it doesn't get any water in it to freeze and crack. I thought I needed to move the filter box into the garage to keep it from freezing, but someone said it wasn't necessary, that the good bacteria would be "dead" anyhow with the colder temps, even if it didn't freeze.
Does anyone have a good size of air pump to get? I've seen others mention anywhere from very small to very large. Again, I will probably put it attached to the fountain area, to keep that pipe "open" from the ice and keep it from freezing, if possible, along with the heater in that area.
