Dock Bubbler - Best Practices

[Lakegeezer]

After a few winters, it seems like a good time to exchange stories again on dock bubblers. Everyone’s setup is a little different, and I’m curious about what people have found works well in real life. How long do you tend to run them, whether timing matters, and how you position or aim the fan. I’m especially interested in approaches that keep docks safe while keeping the open-water footprint as small as practical along the shoreline. Do you let some ice form and clear it as needed, or try to keep things open all the time? If you’ve adjusted your setup over the years based on what you’ve seen, tell us what’s worked for you.
