Nothing like sitting across the water looking at the fishes while you sip your coffee, right? What if I told you that you could get that luxury right in your backyard?
Whether you have a large backyard or small, or whether you have thousands of dollars or not, you can still create a Koi Pond.
Let’s dig right into them.
What Materials Are Used to Construct Koi Ponds?
Despite its roots in Japan, the koi pond idea has expanded quickly worldwide. Adding a koi pond to the landscaping or garden can make your property more attractive and interesting.
However, creating a koi pond requires time, effort, patience, and the appropriate materials. We presume you have already kept the first three factors in hand while reading this section. So, we will discuss the materials used to construct a good koi pond.
Here is a quick list of the materials required to make a koi fish pond with pictures before getting into more detail about what is what.
Pond Underlay
A pond underlay is a protective layer of thick filter cloth used underneath the liner. It is constructed from a nonwoven, needle-punched fabric composed of black polypropylene. Additionally, the underlay may be positioned on top of a bigger rockery’s liner.
When to add? During the construction of the pond.
Pond Liner
As the name suggests, a pond liner is used to line the pond. A pond liner must be sturdy, flexible, and easy to install.
When to add? During the construction of the pond.
Pond Filter
A pond filter is essential to keep the koi pond clean. Just as one would use a filter in an aquarium, koi ponds also need a water filter. The filters are available in different sizes and functions depending on your needs.
But when looking for a filter, choosing one that will effectively clean the pond depends on the total water gallons you intend to use. The filter should also be pressured to efficiently capture dirt, grime, debris, and other materials.
When to add? It is best to include when the pond is being built. However, the filter can also be included after construction.
Pond Skimmer
Pond skimmers are optional. But if trees or large shrubs surround your koi pond, you should take advantage of this element. A pond skimmer helps clean the water surface of large debris like leaves.
Pond skimmers also stop the accumulation of silt, which eventually leads to algae growth at the water bottom. It should be noted that there are many sizes and shapes of skimmers.
When to add? During the construction of the pond.
Pond Pump
A pond pump maintains water circulation, which keeps the water healthy and fresh. Therefore, installing it is crucial when building the koi pond. It should be noted that there are numerous options available when choosing a pump for your koi pond. Additionally, the type of pumps you select should match the function of your installation. This is because some pumps lift water several feet, while others push it only a few feet. Before making a pond pump purchase, you should consider the following three factors:
- How high is the water pumped?
- How much water can the pump move?
- How much room will the waterway have? (in the case of a stream or waterfall)
When to add? During the construction of the pond.
UV Clarifier
Despite being an optional component, it is nevertheless quite helpful. For example, a UV clarifier uses a particular UV light to purify the water in a koi pond. This clarifier emits UV light to destroy mold, harmful algae, and microbes.
When to add? During or after the construction of the pond.
An Aeration System
An aeration system is essential for koi pond oxygenation. The oxygen in your pond is essential to every process. Therefore, keeping the oxygen level in the pond water appropriate and balanced is essential.
An aeration system serves as a backup method to increase the water’s oxygen content during increased heat, at nighttime, and even during winter.
When to add? During or after the construction of the pond.
Tube, Fittings, Primers, Glue, and Hose
When to add? During the construction of the pond.
Ionizer
Ions are discharged into the water by an ionizer through a probe. This element control/eliminate string algae.
When to add? During or after the construction of the pond.
Lighter
Although this is an optional component, we strongly advise it. Your koi pond will look a lot better with pond lighting. In addition, these lights are quite useful if you wish to see your pond at night. For pond lighting, options include LED and Halogen lamps, underwater lights, lamps, etc.
When to add? During or after the construction of the pond.
Note: Even though Koi are tough fish, you’ll still need to give them the right environment to maintain their health. Therefore, choosing the proper materials while building a koi pond is extremely important.

12. Porch Koi Pond
We recently came across this koi pond that was built into a porch and we couldn’t take our eyes off it (nor will your guests be able to).
It had pretty much everything like a waterfall using ornaments in the shape of aquatic animals like a tortoise and a frog. But the best part about it was the lighting.
With a stream of yellow LED bulbs on the edge, it creates a warm environment perfect to sit around with your hubby or friends.
13. A Modern Koi Pond
If you want a more modern finish to your koi pond consider placing large decorative mirrors. This not only makes the interiors and the pond feel bigger but also lets more natural light enter the backyard, indoors, and the pond. And placing you a few decorative stones at the bottom further adds to the depth.
14. A Beautiful Entrance
Forget your backyard or lawn, if you have a mansion with a long walkway entrance, a koi pond is one of the most welcoming things you can include. With some lighting, some rustic ornaments and maybe, even small waterfalls, and plants people will love to walk through your entryway making it one of the most attractive portions of the house.
15. The Glass Koi Pond
Remember we told you about the box raised pond above? This design is similar to that except much easier to look at since the front portion of the pond is glass which makes it easier to get a look at the fishes and the greenery, just like you would in an aquarium. Some ceramic pots with a marble finish on the sides and you are good to go.
16. Simplistic Koi Pond
Don’t want the hassle of maintaining a lot of fishes and aquatic plants? Or may you are cramped for space or on a low budget? This simplistic koi pond is the solution to it all. It can be as big as an aquarium and need not be too deep either (this baby can be up and ready in just a couple of hours). Add a couple of stones and you are done!
17. The Hot Tub Koi Pond
Don’t sell your old hot tub just yet. And do not give it away in the scrap either. Upcycling is the latest trend and it is your turn to jump on the bandwagon and turn your old hot tub into a visual masterpiece.
All you have to do is seal it off on the sides, set up a filtration, get some plants, fishes, and there, scrap turns to gold.
18. Triangular Koi Pond
If it isn’t circular or square, is it still a pond? Absolutely. You do not always need fancy ornaments or a waterfall to make your pond stand out. Something as simple as changing the shape to a triangle or any geometrical design is bound to get people’s attention. Plus, it will be easier to fit it as well.
19. Corner Koi Pond
Whether indoors or outdoors, corners can be hard to decorate, and doing it right creates a flow and continuity that prevents it from looking like a mainstream backyard. Planting is great but how should you do it?
Well, in a way that adds depth and height to the corner and nothing does that better than a pond. And since it is a corner why not go with a triangular pond?
20. Swimming Pool Koi Pond
Can your swimming pool act like both a pond and a pool? Yup, just because you have a pool doesn’t mean you need sacrifice on the pond or the pool itself. Yes, you can set up a pond with all the required filtration and chlorine levels to ensure you get fresh water all the time.
But what about the plants? Won’t the chlorine kill them?
Yes, but if you place them intelligently you can avoid the effects while maintaining the right aesthetics of a pond.
21. Boat Koi Pond
If you don’t already have an old boat considering buying it from a garage sale. We love this one because it is hassle-free since it eliminates the need to dig deep. Plus, a boat is big enough to fit in all the plants you’d want as well.
Oh, and its rustic looks mean you do not need a lot of pebbles and rocks around either (you just got a boat; you’d want to show it off, right?).
22. Simple Koi Pond
You can make your koi pond as fancy as you want with lights and plants, etc. but simplicity has its elegance. With some texture, bold lines in a rectangular shape, and no plants or rocks around it, the koi fish and other fishes are going to be the highlight of this pond and is just what a minimalist would love.
23. Walkway Pond
So far we mentioned having the pond on the side of the walkway. What if you created a walkway on the pond itself?
With some rustic rocks as the walkway, some koi, and golden fishes it is something straight out of a 5-star or 7-star hotel and now right in your backyard. Plus, you can add some waterfalls in the side to add to the glamour.
24. The Funky Koi Pond
You want to make your pond as attractive as possible and this koi pond idea does just that. All you have to do is create a small piece of land in the middle. Now, this can be round and deep like a bucket so it feels like a sunken island with you deep in it making it a truly intriguing piece of PondScape.
25. The Curvy Koi Pond
Rather than just one simple pond, if you have space, why not have 2-3 circular ponds. When you play with different sized circles and other curvy shapes you create more depth. And if you have some tall trees or some wall art that reflects in the pond and rectangular pavers, the contrasting shapes compliment each other well.
26. The Natural Pond
If you want to give the pond a completely natural look there are a few elements you have to get right. For example, a natural pond requires a rocky outcrop, specific wetland vegetation, and some other things that are bound to fall from the trees above like branches and leaves. Just add some lilies and driftwood to it and you will have your natural pond in your backyard.
27. The Balcony Koi Pond
Do only have a balcony and not a yard to work with? No problem, we got you covered. All you need is a small bonsai garden on the balcony. Dig a small hole, place some koi fishes in it, place some small rocks and plants around it, and voila, there’s a koi pond even on your balcony now.
How Large Should a Pond be to Support Koi?
After understanding the basic materials to use while creating a koi pond, it is essential to know how big a koi pond should be. Well, it can be as big as you want it to be, or your property can support it. Nonetheless, remember the bigger the pond is, the more maintenance it needs.
Here, we will talk about the minimum pond size to support koi fish comfortably.
Koi fish require a lot of room. After speaking with specialists and reading customer testimonials, we discovered that a koi pond must be at least three feet deep and over 1,000 gallons in size.
Let’s be clearer. You should maintain your pond at 3 feet deep and 6 feet by 8 feet to meet the minimum size requirement. The pond will contain around 1077 gal. of water and 4–5 average-sized koi fish at this dimension.
But since this is merely the bare minimum, the pond size should increase as the number of fish increases. For instance, you would need to construct a pond with a capacity of about 3200 gallons if you wanted to raise 12–15 koi fish.
You probably believe that constructing a small pond is more cost-effective. But if you add fish later, you’ll need to create more ponds to accommodate them.
The “Minimum Pond Size” must therefore be carefully taken into account. Nevertheless, creating a modest koi pond might seem more profitable. But rest assured that the truth is otherwise.
The presence of a koi pond greatly enhances the visual value of a home, and the desire to add additional fish is quite frequent. Therefore, building a sizable pond now is more cost-effective than building more ponds later.
Keep two simple formulae in mind:
- In 10 gallons of water, 1 inch of koi fish will survive.
- Only four to five koi should be kept per 1000 gallons of water.
What Type of Regular Maintenance is Required for a Koi Pond?
Building a koi pond takes time and effort, as does maintaining it. And, as previously stated, the larger the koi pond, the more maintenance it would require.
That being said, keeping a koi pond clean is something you cannot avoid. Keeping a koi pond in good condition is equivalent to keeping its water quality at its peak. Aside from water quality, a few other factors must also be considered for regular koi pond upkeep.
How about putting our hands on exploring the type of regular upkeep required for a koi pond?
- Feed your koi fish three or four times per day, depending on how old they are.
- Refrain from feeding the koi fish too much.
- Take out any rubbish and leaves.
- Clear the pond of any surplus fish food.
- While feeding the koi, keep an eye on them to see if they exhibit any odd or unhealthy behavior.
- Every week, change the water by at least 10%.
- Vacuum the pond’s bottom.
- Check the temperature of the water.
- Make the skimmer basket clean.
- Clear the filter.
- The pH of the water should be between 7-8. Check it.
- To chill the water during the sweltering summer days, install an aerator.
- The decayed or dead plants should be discarded.
- Make sure every installation is spotless and functional.
