Koi Ponds 101

Before we dive into the cost of building a small koi pond, let’s take a look at the basics. A koi pond is essentially a home for koi fish that is designed to meet their needs while also providing an attractive and serene water feature for your backyard. Koi fish are colorful members of the carp family, and they can grow to be over two feet long. Given their size, koi ponds need to be deep enough to support their growth and provide them with ample swimming space.

The ideal dimensions for a small koi pond are 6-8 feet long, 4-6 feet wide, and at least 3 feet deep. Of course, you can adjust these dimensions to suit your needs and the space available in your backyard. Keep in mind that larger koi need more space to thrive, so if you plan to keep multiple koi fish, you’ll need a bigger pond.

Materials

The materials you use to build your koi pond will impact the overall cost. Here are the main materials you’ll need:

Liner

The liner is one of the most critical components of your koi pond. It will hold the water in place and prevent leaks. You can choose from a variety of materials, including PVC, EPDM, and concrete. PVC and EPDM liners are more affordable, but concrete provides a durable and long-lasting option. A liner for a small koi pond will cost between $200 and $1,000.

Filtration System

Koi fish generate waste, which can make the water in your pond unclean and unhealthy for the fish. A filtration system is essential to keep the water clean and clear. There are several types of filtration systems to choose from, such as biological, mechanical, and UV. A basic filtration system for a small koi pond will cost between $200 and $500.

Pump

A pump is necessary to circulate the water in your pond and prevent stagnation. It also helps to maintain the oxygen levels in the pond, which is crucial for the health of your koi fish. A basic pump for a small koi pond will cost between $50 and $200.

Skimmer

A skimmer is an optional but useful accessory for your koi pond. It helps to remove debris and leaves from the surface of the pond, which can make it easier to maintain. A basic skimmer for a small koi pond will cost between $50 and $150.
