With the freezing weather conditions affecting most of the UK, spare a thought for the fish trying to keep warm at the bottom of your pond. It can be a difficult time of year for the fish in your pond when the weather conditions drop the temperature below freezing, and a difficult time for your pond in general.
If you have installed a new pond this year it’s always a good idea to check over pipe fittings to see if pipes are frozen or even split because of the icy weather. Frozen pipes can literally burst apart as the water expands when frozen. The same effect can also happen to your pond liner. When the surface ice on your pond expands the liner can be pushed beyond stretching capacity and tear. A quick check around the edges of your pond and stopping the pond from freezing over can really make a difference here.
If you install a pond heater, your pond surface will not freeze and you will have the added bonus that your fish will be more active during the winter months so you will be able to appreciate them more.
