What is a Koi Pond?
A koi pond is a water feature that highlights the color and size of koi. It is often merged with other types of water features like fountains and water gardens since the fishes feed on the larvae of mosquitoes. On the other hand, the aquatic plants help filter the fish wastes in the pond.
Did you know?
The largest koi pond was built by accident in an abandoned mall in Bangkok. A pool of water filled the basement of the mall that has caused a massive mosquito problem in the area. To solve the problem, local authorities filled it with koi to let them eat the mosquito larvae.
Considerations in Building a Koi Pond
Building a pond requires more attention than a garden. Different varieties of koi are sensitive to temperature and can grow for up to 3 feet and weigh around 12 pounds up to 90 pounds.
- Depth: The ideal depth of a koi pond can be anywhere between 4 feet to 20 feet. It largely depends on the type of koi that you want to grow. If you want to keep your fish small due to space issues, you should consider domestic koi varieties.
- Space: The space of your koi pond should be enough for the koi to swim around. Otherwise, they may die from stress.
- Location: Some koi ponds are built as part of a front yard landscape, while some serve as a space for homeowners to rest around the water feature.
- Design elements: The elements of the koi pond landscape usually includes the framing materials, the type of fountain or waterfall, plants, underwater lighting, and filtration system.
- Water aeration: Waterfalls are added to most koi ponds to serve as natural oxygen for koi. In the absence of waterfalls, you may also place some pond aerators to keep your koi healthy.
- Predator planning: To keep your valuable koi safe from cats, raccoons, and other predators, you must ensure that the pond is deep enough (4 feet) for them to hide.
- Plant and fish dynamic: Plants help naturally clean the fish wastes in the water. They serve as a natural filtration system and a perfect breeding place for koi.
