In this post, we’ll show you how to create and manage your own pond so that you may enjoy it for years to come!

To Get Started, Here’s What You’ll Need

While you may design your koi pond anyway you like, there are a few items that must be used regardless. The items you’ll need to get started are listed below.

  • Liner: An EPDM liner (45 mils) should be used to line the pond as well as any waterfalls, streams, or other water sources. This cloth is both strong and flexible.
  • Skimmer and Skimmer Pump: The skimmer for your koi pond works similarly to a pool skimmer, pumping water through a basket to gather undesired detritus.
  • Pressurized Filter with UV: A pressurized filter can assist you in keeping your koi pond clean.
  • Solids Handling Pump: This pump can handle tiny particles as well as sludge. This may be placed at the very bottom of your pond.
  • Aerator: To oxygenate your koi pond, you’ll need an aerator. The amount of oxygen in the air varies based on the temperature and time of day. When oxygen levels are low, you’ll need to use your aerator to augment the air.
  • Ionizer: An ionizer releases ions into your pond, as the name implies. String algae can only be controlled and even eliminated via this approach.
  • A float valve or an electronic water level controller will usually be installed in the skimmer to maintain a steady water level.
  • Pond De-Icer: If you live in an area where freezing temperatures are common, you’ll need to use a de-icer to keep your fish alive over the winter.
  • Lighting: You have the option of adding light to the interior or outside of your koi pond. You’ll want enough to be able to gaze at your pond at night.
  • Fish: What good is a koi pond if there aren’t any? You may fill your pond with either goldfish or koi fish, or a mix of both.
  • Plants: Adding plants to your koi pond may improve the ambiance and appearance, but that’s not the only benefit. It also serves as a source of natural oxygen and shade for your fish.

We’ll offer you the equipment to make a koi pond without a waterfall to keep things simple. You’ll need a few more items if you want to add a waterfall to your koi pond.

If you want to make a waterfall, you’ll need the following items:

  • Underlay: The underlay is a thick filter cloth material that is put underneath the carpet to give further protection.
  • PVC Flex Pipe, Fittings, Glue, and Primer: PVC flex pipe will be used to link the pumps to the filtration system and ultimately to the spillway. PVC flex pipe is long-lasting and versatile. PVC fittings are utilized because they are durable and prevent pipes from overheating or freezing. To join the pipes to the fittings, glue and priming will be utilized.
  • Spillway or Up-Flow Filter: In waterfalls, a spillway or an up-flow filter is used to disperse water and generate an equal flow.

Step 1: Assess Your Environment

Choosing a Site for Your Pond

It’s important to choose the ideal location for your koi pond. You’ll want to stay away from any regions with huge trees with tangled root systems. Of course, you’ll want to stay away from any power lines.

Koi ponds with fish and plants thrive in areas with partial sunlight. The sorts of plants you may purchase will depend on where you put your pond. Plant choices will be limited in complete shade, while full sun places risk the water being too hot.

Many individuals like to keep their koi ponds near their homes. If you’re able to, having your koi pond close by enables you to keep an eye on it whether you’re in your backyard or gazing through the window of your house.

Decide on the size of your koi pond.

Making your koi pond too small is a common novice error to avoid. Before you commit, draw a rough outline of where you want the pond to go and how large you want it to be. Remember, you’ll need lots of room for all of the essential equipment, as well as water for the fish to freely swim in and plants to bring it to life!

Although it may seem large, a koi pond of at least 1,000 gallons and three feet in depth is suggested. If you want to have a large number of fish, you may wish to make it even larger. A six-by-eight-foot pond with a three-foot depth generates precisely 1077 gallons, which is a decent starting point.

Step 2: Begin digging

Make sure everything is marked exactly way you want it before you start digging up soil. Measure the length and breadth of your pond and sketch out the precise spot using marking paint. Other pond components, including as the skimmer, falls, and filtration, should also be drawn out.

Allow for some breathing room.

In the long term, having a clean desk will make your job a whole lot simpler. You’ll need some additional area to operate in between the heavy pieces of equipment and moving about the pond.

Remove any vegetation from the area where you’ll be putting your pond. Any grass clippings or leaf mounds that may have blown into your office should be cleaned up.

Remove any furniture, toys, or other items that may have accumulated in the backyard. When the pond is done, you may return everything to its original state.

Build a Pond

Get a shovel and start digging! If you can enlist the support of a significant other or a friend to help you with your project, it will go much faster. Because the pond’s top will be the broadest, begin digging at the border and slope down as you approach the center, if feasible.

Use your imagination to design a unique pond form as you dig. Adding shelves to your pond might give it a unique personality.

Step 3: Arrange the Equipment and Liner

Laying out all of the equipment ahead of time will make the process go more smoothly later. Backfill the skimmer and spillway with water. Get a rough concept of where the flex pipe (if used) will go, which is usually behind any falls.

Add Liner

A strong underlay material, such as a 45 mil EPDM Liner, is required. The liner should be somewhat larger than your pond, with at least one foot extra around the outside, so that you can tie it properly.

Look around before putting the liner down to be sure there aren’t any sharp rocks that might harm the liner.

Gather a few buddies to assist you in rolling out the liner over the hole and gently laying it over the soil. Allow at least one foot of liner to extend outside the perimeter so it may be readily secured.

Step 4: Add the Rocks

Purchase a variety of rocks in all shapes and sizes. You’ll need some huge stones as well as smaller pond gravel pieces. If you’re looking for pond rocks, be sure they’re created for ponds. Any pebbles with sharp edges have the potential to damage the lining.

Begin with big rocks.

Begin by laying your bigger boulders or stones along the pond’s edge on the liner. When arranging your stones, use your imagination to get the aesthetic you want.

Start filling in the smaller areas with the rest of the rocks after you’ve put out all of the huge stones the way you want them. The pond gravel on the bottom level and shelves will assist to create a more natural-looking environment.

Keep one foot of the liner exposed behind the rocks to prevent rainfall from entering your pond. If you’re going to put a waterfall in, put waterfall foam between the rocks to keep the water from sliding through.

Flush out the stones with water and pump out the filthy water for the greatest water quality.

Create a High Ridge

Dig a 3-inch high ridge around the whole perimeter of your pond to keep rains, grass clippings, and other debris out. Shift the soil into a ridge shape against the rocks using a spade.

Incorporate Lighting

After you’ve positioned the rocks the way you want them, start searching for places to put underwater lights. Place the lights away from the primary viewing area while putting them up.

Fill with water in the fifth step.

As you fill your koi pond with water, you can see it come to life!

Fill your pond with water using a hose. Add a de-chlorinator, a carbon charcoal filter, or a water conditioner if necessary to eliminate chlorine. Keep in mind that chlorinated water is hazardous to fish, even koi. If you must treat chlorinated water, make sure you do so before introducing fish to it.

After the fish have been added to the pond, treat the water outside of it before bringing it in. To avoid fish from falling into shock, change the water in lesser quantities at a time in the future.

Make Water Adjustments

Your water’s pH should be between 7 and 8.6. Use a water testing kit to make sure the pH and dissolved nutrients are at the proper levels for your fish. Continue to alter the water’s properties as needed.

Before introducing fish to your koi pond, make sure the temperature is approximately 65 degrees Fahrenheit. Koi fish can tolerate in water temperatures ranging from 34 to 90 degrees Fahrenheit, but they flourish in temperatures around 65 degrees.

Throughout the day, keep an eye on the temperature. An aerator may assist maintain temperatures, but a pond heater might be useful in the winter. If the water becomes too hot, add cold water gradually throughout the day.

Installing Equipment is the sixth step.

Filtration should be installed.

To locate a filtration system, go to a pond equipment provider and carefully follow the instructions. A filtration system will maintain the pond water pure and of excellent quality, ensuring the health of your koi fish.

  • The settling chamber makes it simple to clear trash from your pond and maintain it clean.
  • The mechanical filtration system captures garbage as it floats through the water of the pond.
  • Ammonia and nitrate levels will be reduced through biological filtration, both of which may be poisonous to your fish, such as koi.

Place the Aerator where you want it.

The aerator, as previously said, will keep the pond water circulating. As the weather becomes cooler, this oxygenates your pond, increases gas exchange, and keeps the water from freezing.

Make sure you know the volume, shape, and depth of your pond before buying an aerator to guarantee you purchase the right size.

You probably won’t need a pond warmer if you have a pond aerator.

Before introducing the fish, turn on both pieces of equipment.

Step 7: Include Plants

How to Select Plants

Plants in your pond will help to oxygenate the water and give shade for the fish. For your pond, try to select a mix of surface, emergent, and submerged vegetation.

Having a large number of plants in the pond may assist keep the temperature down during warmer months. You may not need as many plants if your pond is huge and deep.

Here are some of the several sorts of plants you may use in your pond:

  • Submerged Plants: As the name implies, submerged plants are those that grow totally under the water’s surface. Coontail, eelgrass, and pondweed are a few examples. By covering the bottom of your pond with rocks, you may protect the roots. When the fish are hunting for food, this will prevent them from digging them up. These plants are low-maintenance after they’ve been planted.
  • Surface Plants: Surface plants float on the water’s surface and do not need their roots to be buried in soil. These plants provide excellent shade for your fish, keeping them cool throughout the hot summer months. Fairy fern, water shield, and water clover are some examples of this plant.
  • Plants that are rooted in the ground yet have leaves and blooms that are visible above the surface are known as emergent plants. Cattails, blooming rush, and yellow lotus are examples of emergent plants.

When Should You Use Plants?

Plants do not need to be added before the fish, but they should all be added at the same time. If you simply put a few plants in, the fish may get too interested and destroy them. By introducing a large amount of greenery at once, they are prevented from focusing all of their attention on a single plant.

Step 8: Add the Fish

It’s time to put the fish in your pond after it’s all set up and ready to go.

Keep your fish in the plastic bag with the water they came in. Allow the bag to float for a half-hour on the surface of your pond to allow them to gradually acclimate to the temperature.

To help them acclimate, fill the bag with pond water, tie it up, and let it float in the water for another 30 minutes. If it’s a hot day and there’s no shade, you may cover the bag with a towel to protect it from becoming too hot.

You may unzip the bag and release your fish into their new habitat after they’ve accustomed to the pond water.

The Most Appropriate Fish for Your Koi Pond

Despite the fact that it’s named a koi pond, it’s not exclusively for koi. There are a variety of fish that may survive in your pond and perhaps live for 30-40 years!

Here are some of the greatest koi pond fish:

  • Koi Fish: With over 100 different varieties of koi fish to pick from, you won’t be disappointed. Koi fish are very intelligent, and they can even be taught to feed from your hand! If you want to have a bit more involvement with your new pals, this makes them a wonderful pond fish.
  • Grass Carp: The grass carp is a huge herbivorous fish that enjoys eating algae. Now, you would not want to buy too many of them since they have a tendency to eat too quickly. This may swiftly escalate from algae management to ecological disruption in your pond.
  • Goldfish are a popular choice for a koi pond for a variety of reasons. They’re less expensive than other types, keep healthy, and are stunning to watch swim about! You may be able to see your goldfish grow to be over a foot long if you have a bigger pond. The main disadvantage of owning goldfish is how quickly they multiply, so you’ll have to keep track of their numbers.
  • Sunfish, also known as pumpkinseed fish, are an excellent insect-controlling fish. These fish eat largely insects and parasites, although they may also eat the eggs of other fish. Because they multiply as quickly as goldfish, you may not want to buy too many of them.

Step 9: Maintaining Your Koi Pond

Fish Feeding

To prevent overfeeding, just feed your fish once a day. If you overfeed your fish, the remaining food will decompose in the water. This will not only rapidly cloud your pond water, but it will also make your fish sick.

Bad scents in your pond might also be caused by spoiled food and ill fish. Overall, it produces a negative experience in almost every aspect.

If you detect any uneaten food, try to remove it as soon as possible to maintain your pond clean.

Please don’t overcrowd the pond.

Many fish species may breed fast, resulting in overcrowding in your pond. If your pond gets overcrowded, the fish will grow unwell.

You don’t want to have too many fish, but you also want to keep an eye on your pond’s flora. When there are too many plants growing on the surface, it may reduce oxygen levels and prevent sunlight from reaching the water.

Plus, if there are too many plants, you won’t be able to see your fish. What’s the purpose then? A decent rule of thumb is to keep the plant-to-pond-water ratio between 40 and 50 percent.

Clean your pond on a regular basis

It’s excellent to commit to cleaning your pond every day, but if you can do more, that’s even better. Clean up any debris you observe each time you go to appreciate your pond.

The longer debris is submerged in water, the more time it has to decompose and cause damage. Keep your pond clean by removing any sticks, leaves, or other debris that may fall into it on a regular basis.

Using a net to trap plant stuff and prevent it from falling into the pond is one way to make your cleaning operation more manageable.

Obtain the Required Equipment

We won’t go over the necessity of having the necessary equipment since we’ve previously addressed it. However, for the greatest results, make sure you’ve done your homework and know which sorts of equipment are appropriate for your pond.

Ponds and equipment come in a variety of forms and sizes. You’ll need to know the precise size of your pond and which piece of equipment is appropriate for the task when picking pumps and filters.

Read the manufacturer’s instructions carefully to verify that everything works as it should. When cleaning your pond, check to see that all of the moving components are in working order. Make sure the filtration system isn’t blocked by checking it often.

Keep Predators Out of the Pond

It’s possible that you’re not the only one who has been admiring your pond. Unfortunately, predators may enter a pond, and it is your responsibility to keep your fish and plants safe from them.

Keep an eye out for the following predators:

  • Raccoons: You’re surely aware that raccoons will eat almost everything, even the fish in your pond.
  • Birds: Many birds, such as herons and owls, eat on fish. These predators are swift, intelligent, and skilled hunters.
  • Snakes: You may not have to worry about snakes if you have larger fish. If you have little goldfish, though, you’ll want to keep snakes out of your pond. Learn how to keep snakes out of your yard by reading this article.

Even if one of these monsters makes its way into your pond, you can still keep your fish secure.

Here are some ways to defend yourself against predators:

  • Add Deterrents: Dogs are excellent backyard companions for predator deterrence. Labradors and spaniels are the greatest dogs for bird defense.
  • Hiding Places: If you’re intending on adding plants to your pond, you’ve already taken a step in the right direction by providing a hiding spot for your fish. Consider incorporating miniature caves into your pond for further security. Any caverns should be added before the water is added. It’s best if you can position them as deep as possible.
  • While floating mesh or netting is an excellent technique to keep predators away from fish, it might detract from the beauty of the pond. If you’re constantly dealing with predators, though, this is an excellent last option.
  • Decoys: Predators may be fooled by using decoys such as bird sculptures, imitation fish, and even scarecrows. If you’re employing decoys, be sure to change them around every now and again to avoid predators catching on.
  • Purchase a motion sensor that, when triggered, sprays water to drive predators away. While they will most likely go, it will serve as a warning to the fish to hide.
