As we head into the winter months a common question customers typically ask is “What is the best option to keep a hole in the ice on my pond”.
There are two options that we suggest, but first here’s why a hole in the ice is important.
During the winter a hole in the ice allows an area for gas exchange. Decomposition of fish waste and organic material produces harmful gas that can get caught under the surface of the ice. This robs the water of oxygen causing stress to the fish. A hole in the ice allows the harmful gases to escape while also allowing oxygen rich air back into the pond.
What is the best way to keep a hole in the ice?
Option 1: Electric Pond Heater
The name “pond heater” may be a little misleading. The heater doesn’t heat the entire pond, it heats the water around the unit, keeping a hole open in the ice. Some models are thermostatically controlled, while others continue to heat while plugged in. The heater can be a great option if you already have ice on your pond, simply lay the heater on the ice and it will melt a hole down to the water.
Option 2: Aerator
You may be wondering how exactly a pond aerator works. An air pump sits on the side of the pond and pumps air through tubing which attaches to an air stone. This process creates a column of oxygen rich air that rushes towards the surface of the water. The rippling effect helps keep the water from freezing, keeping a hole in the ice.
There is a downside to using an aerator. The air that is being pumped into the pond is the same temperature as the outside air, which will cool the water in your pond. Because of this, you will want to set your air stone about a foot off the bottom of your pond. This allows the warmer water that your fish are hibernating in to remain consistent through the winter season.
It’s worth noting that neither option is 100% fail-proof. During extreme cold temperatures and windy conditions there is the possibility either option could freeze over.
It’s very important to keep an eye on your pond, especially during the winter months. You’ll want to be sure that whatever option you select its keeping a hole in the ice. If you do notice that your pond has frozen over, the best way to reopen the hole is to pour a bucket of hot tap water over the area of your heater or aerator. “Never hit the ice to try to break a hole in it.”
