    Pond Heaters and Pond De-Icers

    When the temperature drops in the winter, it’s not uncommon at all for backyard ponds to freeze. If you don’t have any fish in your pond and don’t plan on running your pond filter system during the winter, you don’t have to worry too much about your pond freezing. Nevertheless, if you do have fish or if you do run your pond filter in the winter, you’ll want to invest in a pond de-icer to keep a small opening in the ice in your pond throughout the winter season. It’ll keep your fish alive through the winter and help you get your pond up and running again in the spring.

    The Benefits of Using a Pond De-icer

    If you’re going to install a backyard pond outside of your home, it’s a good idea to have an outdoor pond heater to go along with it. Without a pond heater, you’re not going to be able to circulate the water in your pond much during the winter since it will likely freeze at some point. You’re also going to have a tough time keeping any fish you might have in your pond alive without a pond water heater in place. We will show you a large selection of ponder heaters and help you find one that will work wonders for your specific pond in the wintertime.

    How a Pond De-Icer Helps Keep Fish Healthy

    Regardless of whether or not you choose to install a pond heater and warm your pond water in the winter, you should always have a pond de-icer set up if you keep fish in your pond. You can use a pond de-icer to create a small hole in the top of any ice that forms in your pond when it gets cold outside. This will enable the proper gas exchange to take place during the winter, which will keep your fish alive. If you don’t utilize a pond de-icer to create this hole, you could very well find that you need to invest in new fish after a long, cold winter season.
