If you are trying to learn how to build a Koi pond, one of the first things you want to do is take a trip to your local garden store and see what they have for supplies and literature on the subject. Many times you can find ready made ponds that are a bit easier to install. It is important to the success of your pond that you build it properly in the first place, so seek expert advice (and installation help) if you are unsure.

The first thing you need to decide is where the pond will be located. Choose a spot that won’t get contaminated with runoff from fertilizers or chemicals you may use in the lawn or garden. You can put it in the shade, but avoid placing it directly under trees since the falling debris will cause you a maintenance nightmare.

You want to build a Koi pond that is as big as possible - this will allow you the most amount of fish and also will be easier to maintain. You want to make your pond deeper if you are in a cold climate so that there will be water in the winter for the fish so you might need a larger size for this.

Once you have outlined the size and shape, dig the hole. You want the pond to gently slope just like in nature so you might leave it shallow on the edges and deeper in the middle. Be sure to remove all rocks and debris from the hole as you don’t want anything there that might pierce your liner.

Next, you want to position your filter, pump and skimmer and make sure they are level. Be sure they can reach an electrical outlet and hide the cords as necessary.

One of the biggest questions in how to build a Koi pond is what to use to keep the water in. You can buy a rubber liner that is specifically made for this purpose. Cut the liner to the shape and size of the pond and lay it in the hole. You can also buy pre-formed plastic liners that are like tubs or those small kids pools - these come in predesigned shapes and sizes and won’t give you the freedom of design that using a rubber liner will, yet they are a bit easier and quite durable.

Next, you want to excavate for your waterfalls or rivers if you have them and then finish if off by placing the stones around the edge to hold the liner in place as well as add character and a natural feel.

Now, the fun part - fill it up! As you are filling the pond, smooth out any wrinkles in the liner and don’t forget to add the dechlorinator.

Finally, turn on the filter and pumps and get everything running properly. Get your pond to cycle through the nitrogen cycle and it will be ready for your first Koi fish.

Now that you have learned how to build a Koi pond - don’t just sit there - go out and build one!
