Building a Koi Pond


Building a Koi Pond


There are many reasons to build a pond in your backyard, though the most common reason would be to raise koi. So, you probably have more than a few questions about the construction of a pool and what you can do to ensure smooth sailing. There are a few things that you will need to consider before you commence its construction and they are the following:

More than Dirt:

Contrary to popular belief, they are not simple holes in the ground. You cannot dig a hole, fill it with water, and hope for the best. At best, it will drain and your fish will die. At worst, the water will become contaminated and your fish will contract some sort of disease. Either way your fish are doomed, and if you want to avoid this, you will need to make sure you create a suitable environment for it.

Filtration Filtration Filtration

Because you’re dealing with an open pool, it is inevitable that debris would enter the water whether you’ve built an outdoor pool or chosen to create one inside. Either way, you should make sure you build a decent filtration system that is capable of filtering out the debris. A good pumping system and efficient settlement chambers will ultimately help you to maintain a good system, and keeping that system maintained will be the difference between life and death for your koi.


90% of the filtration in a good pool can be attributed to the drainage system. For the first 15000 L you will need one drain, and you will need one more for each 15000 L after that. Always make sure that the drains are properly covered and secured as doing so will keep your koi from being sucked into the drain. Trust us when we say that you do not want to clean up that mess at any time in the future.

Deep and Wide

This should be obvious, but ensuring your pool is deep will help you out quite a bit. Your fish need room to move around, and with a larger pool, you can add more aesthetic elements. Remember that a pool does not necessarily need to be an unsightly concrete tank in your garage or backyard! It could be integrated into your home under the floor or even as a part of your front entrance.

Comfort is Key

No matter where you choose to build it, pond it becomes necessary to install a decent climate control system so that you can ensure your fish are comfortable at any time of the year. This is its most important part of the construction aside from the installation of filters and drains! Make sure you get it right the first time.

If you are unsure on any of these points or have more questions, it would be advisable for you to consult with a professional and find out just what you need. This is not a small project and it will take some time for you to get used to the intricacies of owning a koi pond.
