Fountains questions, answered by experts

You have several options for your pond by getting your yard ready for the winter. You can winterize your koi pond by ensuring it’s at least 5 feet deep so it doesn’t freeze completely, installing a pond heater or aerator and having it run at all times, and installing a deicer if temperatures are dangerously low for an extended period. You can also choose to shut down your pond for the winter by removing all the wildlife in it and bringing it indoors, cleaning out the filter and pump, and then covering the pond with a tarp.

Regular water testing, debris removal, and seasonal maintenance ensure healthy water quality.

A koi pond should be at least 5 feet deep to keep the fish healthy and ensure they don’t freeze in winter. Koi fish are also known for growing large, so the more room you have, the better. A larger koi pond size will allow the fish to grow bigger than a smaller one will, and the more fish you have, the bigger the pond you’ll need. Learn how to build a pond in your backyard to ensure it remains functional and aesthetically pleasing for a long time.

Most pond installations take 3-10 days, depending on excavation, liner placement, and filtration setup.

Yes, your fish should stay alive in a frozen pond if you winterize it properly. By ensuring your pond has enough oxygen, good water quality, and a hole to release harmful gases, your pond and fish have the best chance of staying alive and healthy. However, if you have tropical fish, they should be overwintered indoors.
