Q: Can I move my diffuser plates all to the shallow end of the pond so I can skate on the other side?

A: Though it would be nice to have the best of both worlds, a pond that’s aerated with diffuser plates is not safe for ice skating. Here’s why:
The reason you run a diffuser through the winter is to aerate the pond and move the water surface to maintain a hole in the ice, allowing for gas exchange. This ensures the water in your lake is well-circulated and your game fish and other underwater inhabitants have enough oxygen to get them through the cold season.
The trouble is that the ice that forms on the surface of water that has been moving for even a short time can be porous and not suitable for skating. Even movement on one end of the lake and not the other can make the ice at the edges unsafe.
If you want to use your pond for skating, plan in advance. Before the ice forms:
- Shut your aeration system down completely. It’s critical to do this before the ice starts to build on your pond’s or lake’s surface for the safety of those who will skate on the pond.
- Stow components away. Your airline and plate may stay in the pond, but the system’s cabinet and compressor should be stored indoors to prevent condensation and rusting.
- Have an emergency plan, just in case. While you’re prepping your lake for ice skating fun, now’s a good time to make sure you have water safety items available, too, like a Taylor Made Life Ring. If the ice breaks, a safety preserver like this can save someone’s life.
Even if ice skating isn’t your thing, it’s still important to follow this all-or-nothing aeration strategy. Running your system “part time” could cause condensation in the unit from the hot compressor cooling, causing rust to form. It could also allow moisture to get into the airline, which could then freeze.
Bottom line: If you plan on skating on your lake or running your aeration system “part time” for whatever reason, it’s best to shut it down completely. Otherwise, keep it running all season to ensure good water quality for your fishes.
