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.

A koi pond may add value to your home if it’s a feature sellers are looking for. Like pools, ponds can affect your property value depending on their condition, whether they’re a popular selling point, and how well they’re incorporated into your home’s landscape.

Lifespans vary by material and manufacturer, but pond liners last anywhere from 10 to 75 years. For example, polyvinyl chloride (PVC) pond liners have a life expectancy of up to 20 years. Other types of pond liners, including those made of high-density polyethylene (HDPE) and ethylene propylene diene monomer (EPDM), can last 40 to 50 years.

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.
