Fresh Air for Your Koi This Winter Using a Pond Deicer
A pond deicers job is to create a breathing hole on the pond waters surface during the winter. You need to do this on backyards ponds because of gases that build up from decay, uneaten fish food, fish waste, debris like leaves, etc.
There are quite a few different types of pond deicers on the market. When choosing which one to use you should keep in mind your fish load and how harsh of a climate you live in. Someone with mild winters and ice may not need as heavy duty heater as someone in Canada.
Some of the different models we carry are the floating Farm Innovators 200 Watt Deicer, Thermo-Pond Energy Efficient 100 Watt Pond Deicer, and the 250 Watt Thermo-Pond Deicer - Surface/Bottom, all these pond deicers work great for smaller water features. You will need the higher wattage models for larger ponds.
Once you have selected the model for your application the next thing to think about is installation. Make sure to place in the pond before the ice starts to form. Most models are thermostatically controlled so there is no need to worry about wasting money on electricity if it is warm outiside. This will give you peice of mind when it suddenly drops temps and you don't have time to install it, etc.
However if your pond does have ice on it before you could place the decier in the pond you can simply plug in the deicer and set it in the desired location. It will slowly melt through the ice and create a hole. A basic rule it to install it close to your GFCI power outlet so that there is no need for extension cords which can lead to problems.
It is also good to place the heater near a pond edge so get it out of wind chills and work better.
During the winter keep an eye on it and make sure it is working properly. Some are activated by air temperature and some work by water temperature.
If it starts to trip your GFCI outlet then take a look to make sure there are no leaks, or cracks that could be causing short circuits.
All in all pond deicers are pretty simple to install, but a necessity for keep koi and other fish alive during the winter, along with a pump for air.
