Feeding your fish during winter. It starts with learning how to care for pond fish during winter. When water temperatures drop below 60 degrees Fahrenheit, fish start hibernating. Their digestive cycles slow to a crawl. If they eat anything besides cold water food it can get stuck in their gut. This can make them sick or cause them to die.
Take out leaves and debris. It’s best to clean out the leaves and debris. If your pond freezes with a lot of organic matter on the bottom it can be bad. Leaves and such will break down and release gases into the water. They’ll also pile up as sludge, which makes the spring pond maintenance process harder. This isn’t good for your fish.
Trim plants back. Trimming aquatic plants helps keep their growth in check. Your pond will keep looking good too. The cold water bacteria help balance your pond water, keeping it clean, clear, and high-quality.
Add cold water bacteria. Coldwater bacteria survive the temperatures while cleaning your pond water. It makes your pond better for your fish. It also makes spring pond cleaning easier.
Clean and remove the pump, filter, and skimmers. If you choose to leave your pond running, this does the same thing as beneficial bacteria. Keep your pond clean and your fish happy.
Install an aerator or recirculating pump. Aerators and recirculating pumps add oxygen to the water too. You’ll want to move it further up or turn it off for winter. In the wrong place, it can move colder water to where your fish are and this can hurt them.
Add a floating de-icer. De-icers create a hole in the ice. This allows the gases to escape and oxygen to come in. Your fish will love the cleaner water and fresh air. Don’t break holes in the ice! Imagine being half asleep and a giant sledgehammer crashes through your roof. That’s what it would be like for your fish. It can injure or kill them.
