Fountains questions, answered by experts

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.

A good rule of thumb is to change 5% to 15% of your koi pon’s water every week. Partial water changes help keep your koi healthy, and replacing small amounts at a time prevents causing stress for the fish.

Ponds enhance landscapes, support wildlife, and create a tranquil outdoor environment.

Pond installation costs typically range from $1,500 to $10,000. The final price depends on several factors, including the pond's size, the materials used, excavation requirements, and any additional features such as waterfalls, lighting, or specialized habitats for fish like koi.

To maintain your pond, you’ll need to occasionally clean your backyard pond, especially if you have koi fish. Test the water twice a week to make sure your fish have everything they need and always remove visible debris.
