Pond Design: How to Design a Koi Pond 0 1146

While keeping koi carp doesn?t have to be difficult, getting the design of your pond right and ensuring that it is suitable for koi is really important. There is much more to building a good koi pond than simply digging a hole in the ground and filling it with water!

However you wish to set up your pond, however many fish you intend to keep and however much space you have available, there are several common elements of pond design that you should always consider in order to ensure that your eventual koi pond is suitable for your fish.

In this article, we will explain the key elements of pond design and help you to ensure that your koi pond can adequately provide for the needs of your fish.

Koi pond surface area

The surface area of your koi pond will need to be fairly large in order to provide enough oxygenation, and allow your fish room to grow. Aim for as large a surface area as possible, and 100 square feet as a minimum.

Water volume required for koi carp

You should ensure that the total water volume of your pond is not less than 1,000 gallons at an absolute minimum.

Your koi pond should not be a uniform depth; the base of the pond should be graduated, creating deeper and shallow areas. Provide at least one deep area of 6 feet or more, and some shallows of not less than 2-3 feet deep.


Ensure that you have adequate provision for plumbing lines and getting water to your pond; you will need flexible hoses, access to a tap, and easy access to all of the pond?s plumbing in case of any problems.

Water movement

You should provide at least two water pumps at different points in the pond, to keep water circulating. Ensure that there are no dead spots of stagnant water. Air stones and other equipment to provide oxygenation to the deeper levels of the pond are also essential.

Algae control

You may wish to install a UV sterilizer in order to keep the growth of algae, plankton and bacteria under control, as micro-organisms will thrive in the pond environment on the waste generated by your fish.


Depending on the climate in which you live, you may need to make provision to heat your pond during the colder months. While koi carp are coldwater fish, they will not thrive in extended periods of bitterly cold weather, so take this into account.


Filtration is vitally important for koi carp, as they generate a lot of waste! As well as planting plenty of koi-suitable plants to help to filter waste and maintain the water quality, you will also need to account for manual filtration, such as by using a gravity-fed filter system, bead filters, and biological filtration.

Keeping exotic fish as pets 0 1869

Exotic fish

There’s something mesmerising about watching a tank full of brightly coloured fish swim around. Do they make good pets though? Is it hard to keep exotic fish? With the right pet care and pet advice, exotic fish make great, if unusual pets.

Tank size

Go for the biggest sized tank you can afford and have room for. The bigger your tank, the easier you’ll find keeping the balance of the water right. Your fish need plenty of room to swim too. Aim for at least a 20-gallon tank.

Tank set-up

You’re going to need a heater to warm the water. You’ll also need a filter to ensure clean, healthy water, which is crucial for fish to thrive. It’s advisable to add an air pump to boost the oxygen levels.

You’ll also need a light for the tank, and a timer for the light, so it’s not on all the time. Bear in mind a fish tank should be placed out of direct sunlight, away from draughts and heating sources.

On top of the things that make your tank work you’re going to need everything that goes into your tank; gravel for the bottom, plants, and decorative caves and tunnels so your fish can hide if they want to.

You can usually buy aquarium starter kits at pet food stores if you want help in pulling everything together.

Getting the water right

The filter will cycle your water to make it suitable for fish to live in, never add tap water directly to the tank. You need to de-chlorinate it first. You can also add a water treatment to help keep the water healthy between changes.

You should change about 10-15% of the water each week to keep it clean and healthy for the fish. Never do a full tank change once your fish are in the tank.

Choosing your fish

When you choose your fish, make sure you start introducing them slowly – this will help you identify if you’ve got the water balance right, and at this point, your tanks eco-system is still developing, so adding lots of fish can damage it.

There’s a wide range of tropical fish to choose from – Cichlids, Betta and Swordtails are good starter fish, and are nice to look at. Never mix goldfish and tropical fish together.
