Building a pond can be an exciting project, but it's important to consider the environmental impact of the materials used. Plastic pond liners, for example, can leach plasticizers that are harmful to aquatic life and the ecosystem. To build an eco-friendly pond, one can consider using alternative materials such as clay, concrete, or fiberglass. Additionally, choosing the right location and size, ensuring proper water sources, and selecting suitable plants are crucial steps in creating a thriving and sustainable pond ecosystem.

What You'll Learn
Choosing a spot and digging a hole
When choosing a spot for your plastic pond, it's important to consider the amount of sunlight the area will receive. While full sunlight all day is not necessary, the pond should get some light to support the growth of plants and wildlife such as tadpoles and dragonflies. Mark the spot you've chosen by outlining it with a rope or hosepipe.
The next step is to start digging! The size of your hole will depend on the size of the pond liner you've chosen. It's a good idea to keep your pond less than the maximum size of the liner to avoid any issues with the liner not fitting properly. For example, if you have a 2.5x2m liner, you might want to keep your pond less than 1.5x1m and no more than 50cm deep. Use a spade or a mini-digger, depending on the size of your pond, to dig the hole, making sure to dig straight down to ensure solid walls that won't collapse later.
As you dig, use a plank of wood and a spirit level to ensure that the sides of the hole are level. Remember to include some shallow areas to create a sloping 'beach' that will allow wildlife easy access in and out of the pond. Remove any crumbly topsoil to a width of 4-5 inches around the hole to create a solid foundation for the pond liner and any bricks or rocks you'll be using to decorate the pond. Check for rocks and roots that may puncture your liner, and use your hands to feel around the hole to remove any small rocks.
Once you're happy with the size and shape of your hole, it's time to prepare for the next step: installing the pond liner.

Adding a pond liner
When adding a pond liner to your plastic pond, it's important to have a pond design plan in place. For instance, ensure that you have prepared your hole and roughed in the plumbing for the pond. If you have any pipes or fittings that run under the liner, such as in a bottom-drained koi pond, it is especially important to have these in place before installing the liner.
Before installing the pond liner, remove any sharp objects from the pond base and walls, such as rocks, roots, and sticks. If you are unable to remove a sharp item or have very uneven terrain, consider putting down a layer of fill material like soil or sand first to level things out. If you have any voids greater than 1” in size on either the pond floor or the walls, fill them in with dirt or expanding foam to create a smooth backing for the liner.
Next, place the liner in the pond hole, ensuring it fully conforms to the bottom contour of the pond, including around any shelves. Check that you have at least 1’ of extra material around the entire top edge and enough material to reach the top of the waterfall filter. If you are using an EPDM rubber liner, use a geotextile underlayment before installing the pond liner. Once you are happy with the placement of the liner, start folding and pleating the liner to get rid of any bunches.
Finally, backfill the trench around the edge of the pond with soil. Place turf, soil, or flagstones over the exposed liner at the pond edges to protect the liner from degradation due to sunlight.

Adding gravel, rocks, and plants
Choosing the Right Gravel and Rocks
Select gravel and rocks of various sizes, from large rocks to small gravel. This variation will create a natural-looking landscape and provide different functions within your pond. The large rocks can be strategically placed to create hiding spots for fish, while the gravel can be used to fill in the spaces between and create a protective layer over the pond liner.
Preparing the Pond Bed
Before adding gravel and rocks, ensure the pond bed is ready. Install any necessary equipment, such as filtration units, and consider adding a layer of sand or a substrate to provide a base for the gravel. If you plan to include plants directly in the gravel, create planting pockets or small crevices where the plants can take root.
Adding Gravel and Rocks
Spread the gravel evenly across the pond bed, ensuring it covers the liner adequately. Place the larger rocks first, arranging them in a way that creates nooks and crannies for fish to hide and for plants to establish their roots. The rocks should also be used to create different depths and levels within the pond, providing easy access for creatures to enter and exit.
Selecting Pond Plants
Choose plants that are well-suited to your pond's conditions and ecological state. Native species are often a good choice, as they are adapted to the local environment and will support the surrounding wildlife. Consider the size and growth habits of the plants to ensure they don't take over the entire pond. Avoid planting aggressive spreaders like lotus and water lilies directly into the gravel, as they can quickly dominate the space.
Planting and Spacing
Carefully plant the selected pond plants, following the guidelines for each species. Some plants may be placed directly into the gravel, while others may require pots or lily baskets. Space the plants appropriately, allowing for their growth and ensuring they don't crowd each other. Remember that plants will contribute to the overall aesthetics of your pond, so consider their visual appeal and arrangement.
Maintenance and Care
Regularly monitor and maintain your pond to ensure its health and balance. Keep an eye out for dead organic matter and encroaching vegetation. and the buildup of solids like fish waste and uneaten food. Remove leaf debris and excess plant materials with a pond skimmer to prevent water quality issues. Prune and thin out plants as necessary, especially during dormant seasons.

Filling the pond
Firstly, if you are using tap water, it is recommended to let it stand for a few days before adding it to the pond. This is because tap water may contain chemicals that could be harmful to the pond's ecosystem. By letting it stand, you allow these chemicals to dissipate.
Next, begin filling your pond with clean water from a garden hose. Adjust the liner edges as needed while the pond fills. It is important to ensure that the water level does not exceed the height of the liner, as this can cause the liner to stretch and sag. Fill the pond about halfway, and then turn off the hose.
If you are using a pond fountain or pump, now is the time to place it in the pond and test it out. Adjust the height if necessary, using bricks or other supports. It is also important to test the pump before filling the pond, to avoid the hassle of removing the water and fixing the pump if it is faulty.
As the pond fills, place turf, soil, or flagstones over the exposed liner at the pond's edges to prevent the liner from degrading due to sunlight exposure. Additionally, gently place rocks or logs around the sides, allowing them to overlap the edges to create a natural look and provide habitats for pond-visiting creatures.
Finally, once the pond is filled to the desired level, plug in the pump and enjoy the soothing sounds and visuals of your new plastic pond!

Maintaining the pond
Maintaining a pond is essential to ensure it remains a healthy ecosystem for wildlife. While a well-planted pond shouldn't need much maintenance, there are some important things to keep in mind. Firstly, be mindful of the water quality. Aim to replace at least 20% of the water each month to avoid stagnant water and reduce nitrates that contribute to algae formation. If possible, use rainwater instead of tap water, as it contains fewer chemicals.
Regularly remove any decaying debris, fish waste, and uneaten food from the pond's floor to prevent water quality issues and maintain a balanced ecosystem. You can also add beneficial microbes, such as Aquascape's Beneficial Bacteria, to support this balance. Additionally, use a pump to circulate the water and ensure it passes through a filter. The pump should be sized appropriately to circulate the entire water volume of the pond at least once every hour.
Keep the pond well-planted to prevent erosion and maintain water clarity. Aim for 40% to 60% of the water's surface area to be covered or shaded by aquatic plants. These plants act as natural filters, absorbing excess nutrients that could otherwise contribute to algae growth. Opt for a variety of plants, including waterlilies, marginal plants, floaters, and submerged plants.
Finally, be mindful of the number of fish in your pond. Overpopulation can lead to water quality issues due to excess waste and overfeeding. As a rule of thumb, aim for no more than 10 inches of fish for every 100 gallons of water. If you wish to have more fish, consider adding a wetland filter to offset the impact of overpopulation.

Frequently asked questions
Choose a spot that gets light, but not full sunlight all day. Mark out your pond on the ground with a rope or hosepipe, then get digging! Ensure that the sides are level as you dig by placing a plank across the pond's hole with a spirit level on top. Remember to include some shallow areas with a sloping 'beach' to allow wildlife easy access in and out of the pond.
You will need a pond liner, sand/liner underlay, bricks, landscaping rocks, a pump, and a fountain (optional). You can get a pond liner that is 2.5x2m for $39.
First, dig a hole based on the size of your pond liner. You want to dig the sides straight down, but be careful that you don't break off parts of the wall. Then, place your pond liner in the hole and place your layer of bricks around the ledge. This will allow you to have the water level above the liner. Finally, fill your pond with rainwater, as tap water contains chemicals.
Great plants for small ponds include miniature waterlily, lesser spearwort, starwort, and flowering rush. Carefully selected native species will support your local wildlife.
If plants are well chosen and the pond is kept in a relatively balanced ecological state, it shouldn't need much maintenance. However, do keep an eye out for a buildup of dead organic matter and encroaching vegetation.
