Fountains FAQs, answered by experts

How many fish can call your pond home depends on the volume of the pond and the fish size. Your pond's filtration system also influences the number of fish that will thrive in a pond. A general rule of thumb is to have 1 inch of fish for every square foot in a pond that's 2 feet deep. Another rule of thumb you can follow is to have one koi fish for every 200 gallons of water or two goldfish for every 200 gallons.

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.

One of the most important parts of building a pond is digging the right depth. Your pond needs to be at least one to two feet deep. The specifics of the depth will depend on factors such as the placement of the pond and whether you plan on having fish. If you have fish in your pond, it will need to be at least two feet deep.

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.

Though there are a lot of factors that go into caring for a koi pond, the most important maintenance you can do is frequent water checks using a koi pond test strip that checks the water for dangerous conditions.  In addition to regular pond maintenance costs, you’ll also need to winterize your koi pond if you live in a colder area.
