Large pond in the garden

Large natural pond

For a pond with a volume of 10,000 liters of water or more, it is referred to as a: 'large pond'. A pond of this size provides enough room for a variety of aquatic plants and fish and can be a prominent feature in a garden or landscape. It is important to realize that a pond of 10,000 gallons or more typically requires more maintenance than a smaller version, unless you properly design the natural pond so that you create a self-sustaining water feature. It is essential to maintain balance and water quality to ensure the well-being of the aquatic plants and animals in the pond. When properly designed, the pond will naturally self-maintain itself, eliminating the need to install pumping and filtration systems.

Digging a large pond

Constructing a natural pond

Constructing a large pond offers an ideal combination of natural beauty and sustainability. Coupling stylish design with the power of natural filtration, a large pond is an environmentally conscious and virtually maintenance-free alternative to ponds with pumps. Everything starts with thorough preparation: from selecting the right digging materials and pond liner to choosing the perfect aquatic plants. We offer a detailed guide to building your large pond yourself. Our additional tips will help you get the most out of this natural oasis. Enjoy the tranquil waters without worries, while local wildlife is at ease in the plant filter and nature takes care of the heavy lifting.

1. Planning and design

  • Determine purpose: First, determine the purpose of your large pond. Is it primarily for viewing or do you want to promote biodiversity in and around the pond at the same time?
  • Location: Choose a location that is partially shaded and away from trees and shrubs that can drop leaves and debris into the pond. Also check that the ground is stable and suitable to support the pond.

2. Digging the pond

  • Dig the pond according to your design. The depth of the pond depends on your preference and intended use. Commonly chosen depths are between -1.50 and -1.80 m.
  • Provide solid walls, especially if the pond is deep, to avoid collapse and problems with groundwater.
  • Take into account a possible plant filter. A good depth for this is -40 cm from the water level.

3. Pond liner installation

  • Apply a quality rubber liner (such as EPDM) that is durable, stretchy and suitable for the shape and size of your pond. This liner helps retain water and prevents leaks. Make sure it is evenly distributed and not pulled tight. Cut off the excess liner and cover the edges with rocks or other decorative material.
  • Finish the foil well at the edges with hardwood cover battens or stones, for example.

4. Setting up the plant filter

  • Place a 20 cm layer of pond substrate in the filter section of your large pond.
  • Plant water purifying plants in this layer, followed by another layer of substrate of about 10 cm.
  • The plant filter will serve to purify the water naturally. The plants will have to grow first before the filter works optimally.

5. Maintenance and heating

  • A natural pond requires minimal maintenance. However, occasionally you should remove twigs or leaves and prune the filter plants.
  • Also consider accessories such as a dock with lounge area so you create a perfect place to sit next to your large water feature and enjoy the pond daily.

Large pond planting plan

We give you information about planting options for a large pond, without the need for pumps, filters or water conditioners to keep the water clear and healthy. With our planting plan, you can design your pond so that it maintains itself naturally and you have minimal maintenance.

1. Pond substrate: for a good start

Pond substrate

It is very important to get off to a good start when setting up a pond to avoid future problems. Especially with a large pond this is important because this is a large pool of water that requires a lot of maintenance if you set up the pond correctly. A low pondsubstrate at the bottom provides a natural and stable base. This is because the pond substrate attracts good bacteria that keep the water clear. Substrate also ensures that plant roots can take root better so that the aquatic plants can perform their useful functions in the pond. Because our substrate consists of porous stone grains, it is low-maintenance and lasts a lifetime, making it a very good investment.

Simon's advice for a pond substrate

Use 40 liters of substrate (2 bags) per m2, leaving a layer of 8-10 cm of substrate on the pond bottom

POND SUBSTRATE Pond substrate - 1000 liters

- 1000 L covers 10 m² ↥ 10 cm
- Heavy duty quality for the best filtration
- Extra porous: optimal plant growth

2. Oxygen plants: keep water clear and healthy

oxygen plants

Are you experiencing algae blooms in your large pond, especially during the summer months? This is a common problem in natural ponds. Algae is not only unattractive to look at, it also removes all oxygen from the pond water, which can cause plants to die. An effective solution is to introduce loose oxygen plants or oxygen plants in baskets. These plants convert carbon dioxide in the water into oxygen, thus controlling and preventing algae.

Simons advice for oxygen plants

Minimum: 1 basket with 4 oxygen plants and maximum 4 baskets with 16 plants per m³ (1000 liters of water) + 5 to 6 loose oxygen plants.

3. Sumpfpflanzen: naturally filter the water of waste products

Sumpfpflanzen category

Sumpfpflanzen purify and filter the water in ponds. By placing these grass and reed-like plants, you ensure that the pond is complete. Thanks to their strong root systems, Sumpfpflanzen grows quickly and roots firmly into the pond bottom, from which they get their nutrition. In addition, Sumpfpflanzen are hardy. Hardy means that they can survive cold weather with frost and do not require covering.

Simons advice for Sumpfpflanzen

Minimum: 16 plants per m²

4. Water lilies: prevent algae with a water lily

Pond with water lilies

For an ultimate and colorful large pond, water lilies are indispensable. These hardy plants come in a variety of shapes and sizes, suitable for different depths. With their large leaves, they not only block out sunlight from the water surface, which prevents algae blooms and prevents excessive warming of the water, but they also provide an ideal hiding place for pond animals such as frogs, salamanders and toads. Like our other water plants, we supply the water lily including basket, which makes planting easier. A water lily can be planted to a depth of -100 cm and provides a lively and healthy dynamic in your large pond.

Simon's advice for a water lily in your large pond

At least 1 water lily per 0.5 to 3 m²

Water Lily Field - 6 pieces - Nymphaea Drop & Grow

- Large water lily
- Without basket into the water
- Placement: -10 to -100 cm

5. Pond bacteria

Bacta Clear for a clear pond

Finally, it is important to add a bottle of Bacta Clear to the pond water twice a year. This is because this unique formula, together with the different types of aquatic plants, ensures that the pond remains clear and balanced. It contains two types of bacteria that remove waste products from the water. This increases the oxygen level in the water, which in turn helps promote the growth of pond plants, keeping them strong and healthy. One bottle of Bacta Clear pond bacteria is suitable for ponds up to 20,000 liters, your large pond contains more than 20,000 liters, then add extra Bacta Clear.

Simon's advice for pond bacteria in a large pond

Add 2x a year (1x in spring and 1x in fall)


- For 1,000 to 20,000 L
- 100% eco: clear water fast
- Safe for humans, plants & animals

3 tips from Simon for implementing the roadmap

Planting plan for a pond without pump and filter
  1. Unfortunately, a common mistake: the pond is already filled with water while the pond plants have yet to be placed. This makes it difficult or even impossible to place all the plants in a good, sturdy spot. Simon therefore recommends starting first with a thin layer of pond substrate in an empty pond, after which you only allow a small layer of water into the pond. You can now step through the pond with boots on to place the aquatic plants in place in the substrate. Then top up with substrate. Is everything set and firm? Only then fill the entire pond with water.
  2. If you have a somewhat larger pond, it is smart to work from the inside out. So you start in the lowest zone and work outward step-by-step. You end in the shallowest zone (swamp zone).
  3. When placing the aquatic plants, also pay attention to what depth is best for optimal growth. This is indicated on the packaging of our pond plants. Do you like a lot of plants? Then place the baskets or crates against each other.

Frequently asked questions about large ponds

Pond Advice

The cost of a large pond depends on the cost of building and decorating the pond. If you decorate the pond with aquatic plants to filter the water naturally and do not use pumps and filters you will be a lot cheaper and contribute to the environment!

The amount of water needed per square meter of floor space depends on the depth of the pond. Generally, for a pond with a depth of about 50-60 centimeters, a volume of 1,000-1500 liters per square meter is recommended. This means that for a 10-square-meter pond, the amount of water needed would be about 10,000-15,000 liters.

If you choose to keep fish in your pond as well, it is important to size the pond accordingly. For the fish to overwinter safely, the pond should have a minimum depth of 80 cm. In addition, it is advisable to match the size of the pond with the types of fish you want to keep.

Building a large pond near your home does not require a permit, unless it will be located in your front yard. By law, this refers to an area within 30 meters of your home. However, if you have a spacious yard and place the pond 50 meters from your home, then a permit is required.

An average pond is about 80 - 100 centimeters deep. Small ponds are usually around 60 centimeters deep. A koi pond and swimming pond are often much deeper (usually around 150 centimeters deep).

Large garden pond landscaping

Setting up a large pond requires many aquatic plants. It is therefore ideal to buy plants in large numbers in the form of a pond plant package. One plant that should not be missing from any pond is the water lily. This is because water lilies are not only beautiful to look at, they also have several useful functions. The leaves of the water lily filter sunlight, which reduces water heating and algae growth. In addition, the leaves of the water lily provide a natural hiding place for fish and other aquatic inhabitants. For a large pond, 1 water lily is obviously not much, for this type of pond a water lily field consisting of 30 water lilies is therefore the ideal choice. Our water lilies are hardy, which makes them a good investment for a clear and healthy pond for years to come.

Constructing natural natural pond without liner

When constructing a natural pond, it is important to choose a sunny spot with at least six hours of sunlight per day for pond plant growth. An existing pond or ditch is often used to supply water. After the contours of the natural pond are dug out, water can be directed from the existing water feature to naturally maintain the water level at the proper height. The deepest part of the pond should be -1 to -2 m, and if you want pond fish to swim around in the pond, the pond should be at least -80 cm deep.

What is a natural pond?

A natural pond is maintained naturally without the use of chemicals or mechanical devices such as pond filters or pond pumps. The pond can be filled with rainwater, groundwater or tap water and constructed with different materials such as rocks, stones, sand, clay and of course: many and different types of aquatic plants. A natural pond provides space for aquatic plants and pond animals to live and grow and can serve as an aesthetic addition to the garden and natural habitat for animals promoting biodiversity. Pond maintenance can vary, depending on size and conditions, and includes regular removal of dead plants and leaves, water replenishment and management of sunlight and shade. Unlike an organic plant pond, a natural pond does not require pond liner, pond substrate and pond bacteria and comes into biological balance through nature and primarily just the pond plants.
