Preparing your Pond for Winter

Posted by on Dec 11 2020

If you have left preparing your pond for winter until the last minute the good news is that it is not too late to protect your pond this winter. With pond heaters, pond covers and more, you can give your fish pond the best protection from everything that comes along with the colder months. Here’s everything you need to prepare your pond for winter and protect your pond’s fish life.

Give your Pond a Clean Before the Temperatures Dip

When preparing your pond for winter, ideally it is worth giving your pond a clean before temperatures reach too low a level. This is because your fish are more active in warmer temperatures and so are less likely to sustain an injury during the cleaning process. Use a fish pond net to scoop out any leaves or debris that may have already fallen into your pond and give the pond floor a quick vacuum with a pond vacuum to clear any extra grime from your pond before winter sets in.

Install a Pond Heater

One of the easiest ways to keep your fish pond safe during winter is to install an outdoor pond heater in your garden pond. During winter, temperatures outside can often dip below freezing causing ice to form on the surface of your pond. If this happens, it can often restrict the amount of oxygen entering your pond which of course is not healthy for any fish living there. A garden pond heater is ideal for regulating the temperature of your garden’s pond during the winter months and keeping it warm enough for any fish life to survive below the surface. Your pond heater will avoid your pond water freezing solid allowing enough oxygen to enter the water to keep your pond fish healthy and happy during the colder months.

Pond De-Icers for Winter

Similar to a pond heater, pond de-icers can defrost your pond when temperatures dip and allow the oxygen to enter the water to keep any fish that may live in there healthy. Our Hozelock Floating Ice Preventers float on the surface of your pond in order to stop ice from forming on the surface and avoid any toxic build-up of gasses under the surface of the ice in your pond. If your pond has already frozen over, the most important thing is to not smash the ice yourself, this will shock the fish which can be fatal. Instead, slightly warm the top of the ice to create a gap for any toxic gasses to escape.

Protect Your Pond Equipment

Whilst there are some things you should add to your pond to protect it over the winter, there are also some things you should remove. Low temperatures can damage your pond filtering equipment as well as your filters and other mechanisms mixing cold water from the surface of your pond with the warmer water at the bottom, not great for any fish you may have living in your pond. When removing your pond equipment, be sure to drain any water from them and give them a quick clean before replacing them in the spring. A good tip for submersible pumps is to store them in a bucket of water in a warm place to avoid them drying out before being added back to your pond in the spring.

Cover your Pond With a Pond Cover Net

During colder months, ponds can often be affected by a build-up of fallen leaves and other items entering the pond area. Our pond cover nets are ideal for preventing this and avoiding a large-scale clean-out once the weather warms up again as well as preventing algae build-ups from decaying leaves that have fallen into the pond. Your pond cover net will also prevent any predators from being able to access your fish in the pond so is a great tool for all the year round.
