Best option to easily add pond plants to your pond without allowing your fish to destroy the plants.

Simon van der Velde

We understand how challenging it is to go from a Fish pond with only pond pumps and filters to a self-regulating, maintenance-free Fish pond with plants.

 

An important component that should not be overlooked: Does your Fish pond contain fish that destroy or eat plants? After all, this greatly affects the setup.

 

With our creative solutions, despite your fish destroying plants, setting up a Fish pond becomes fun again.

Plant filter tower

Most fish and koi ponds contain around 5,000L. It is then nice to add some plants to this large pool of water as well. Our Plant Filter Tower consists of stackable crates with in the top crate 6 baskets full of plants. These plants stand with their roots in the water, while the crate protrudes 1 cm above the water. This keeps the roots protected from fish, while the crates invisible become once the plants start growing.

With these towers you can create a green "wall" in your pond to screen off part of the pond. This also allows you to safely place plants behind this screened "wall" such as a beautiful water lily. Not only do the plants provide a beautiful look, they also filter the water, helping to prevent algae.

Would you prefer a subtle addition? Then place one Plant Filter Tower in the middle of your pond as an eye-catching ornamental piece. This way you combine greenery and functionality without your fish destroying the plants.

P.S.: If you use substrate, a bottom drain is not necessary. In fact, substrate filters the water and ensures healthy plant growth. Substrate is therefore a must-have in a Fish pond.

Tip: Do you have a deep pond? Order additional loose crates to raise the towers easily and stably.

Fish pond docking

A Fish pond is a wonderful addition to your garden and provides a healthy habitat for fish. Here is a practical step-by-step plan for building a Fish pond yourself, based on the best tips and advice.

Floating aquatic plants for fish

Fish pond self-construction in 7 steps

  • Step 1: Determine the ideal location
  • Step 2: Choose the size and depth
  • Step 3: Dig and prepare the pond
  • Step 4: Fill the pond and install the system
  • Step 5: Planting and landscaping
  • Step 6: Add the fish
  • Step 7: Maintenance and monitoring

Step 1: Determine the ideal location

  • Sun and shade: Choose a spot with at least 4 to 6 hours of sunlight per day, but avoid full sun to reduce overheating and algae formation.
  • Safety: Avoid a location under trees to minimize leaf fall into the water and maintain a safe distance from children and pets.
  • Accessibility: Make sure you have easy access for maintenance work.

Step 2: Choose the size and depth

  • Size: Choose a pond of at least 5 m² for adequate oxygenation and swimming space for the fish.
  • Depth: Provide a depth of at least 80 cm to 1.5 meters, depending on fish species. For larger fish such as koi , a depth of 1.5 meters is ideal.
  • Depth zones: Create plateaus with different depths for plants and hiding places for fish.

Step 3: Dig and prepare the pond

  • Excavation: Use a shovel or excavator to dig out the pond according to your design. Make the edges sloping for a natural look.
  • Protect soil: Remove sharp stones and roots. Place a protective fleece before placing pond liner to prevent damage.
  • pond liner: Use EPDM foil or PVC foil at least 1 mm thick for a durable and waterproof bottom.

Step 4: Fill the pond and install the system

  • Fill: Fill the pond slowly with water to allow the liner to settle properly. Preferably use tap water or dechlorinated spring water.
  • Filter system: Install an appropriate filter system to ensure water quality. A pump with UV filter prevents algae formation and keeps the water clear.
  • Aeration: Add an air pump for sufficient oxygen in the pond, especially in the summer months.

Step 5: Planting and landscaping

  • Shoreline plants: Choose native, oxygen-rich plants such as elodea densa and pond weed. These contribute to a healthy water balance.
  • Depth zones: Place plants in baskets at appropriate depths. Use pond substrate for good root growth and water filtration.
  • Shelters: Add rocks, plants or special hiding places where fish can retreat.

Step 6: Add the fish

  • Allow the pond to stabilize: Wait 1 to 2 weeks after filling to allow the water to stabilize and the filtration system to get going.
  • Acclimatize: Float the fish in a sealed bag in the pond to gradually acclimate them to the water temperature.
  • Types of fish: Choose fish species that fit the size of your pond, such as goldfish, windes or koi. Keep about 50 gallons of water per small fish and 500 gallons per koi .

Step 7: Maintenance and monitoring

  • Water quality: Test water parameters (pH, ammonia, nitrate) regularly to identify problems early.
  • Cleaning: Remove excess plant debris and dirt to keep the water clear.
  • Seasonal maintenance: Ensure an ice-free opening in winter and check for algae in summer.

A well-designed Fish pond requires adequate space for the fish and a well-designed pond or plant filter. With these guidelines, you will create a healthy habitat for your fish.

Frequently asked questions about fish ponds

Pond Advice

A Fish pond should be at least 5 sq. ft. to provide adequate swimming space and oxygenation. For large fish such as koi , 10 m² or more is recommended. Keep in mind at least 50 liters of water per small fish and 500 liters per koi.

A Fish pond should be at least 80 inches deep. For fish that hibernate or larger species such as koi , a depth of at least 5 feet is needed to reduce temperature fluctuations.

Use a filtration system to remove debris and algae, install a UV filter against floating algae, and provide plenty of oxygen-rich plants. Remove leaves and other debris from the water regularly.

Popular fish for a Fish pond are goldfish, windes, shubunkins and koi. Note that koi require larger ponds and do not mix well with delicate aquatic plants.

The number of fish depends on the size of your pond. Keep about 50 liters of water per small fish, such as goldfish, and at least 500 liters of water per koi. Overcrowding can lead to poor water quality and stress on the fish.

Fish pond or a pond to fish in

There are two situations when people talk about a Fish pond: when they want to fish in it and when they want to keep fish in the pond. However, they are two completely different things. A Fish pond is basically a pond designed and constructed to raise or keep fish. It is intended as a habitat for the pond fish, and the environment and water are managed to keep the fish in optimal conditions. These ponds are usually larger and deeper than ponds for fishing. On the other hand, a pond for fishing is designed for the angler. It is usually smaller and shallower than a Fish pond and is designed to provide a challenge for the angler. Fish stocks are often used that are stocked specifically for it, so there is a greater chance of catching them. The environment and water are modified to encourage the fish to bite. So a key difference between these two types of ponds is the purpose: a Fish pond is intended to raise or keep fish, while a pond for fishing is intended for sport fishing. Other differences include the size, depth and environment of the ponds.

Fish pond without pump

It is not necessary to install a pump or filter in a Fish pond, whether it is a natural pond, a small pond or any other type of pond. Your Fish pond can thrive extremely well as long as your pond is set up correctly: According to our Step Plan, with enough oxygen plants placed, have a bottom with pond substrate and add pond bacteria in the spring and fall. In such cases, your Fish pond can maintain itself just fine.

The best fish for in a Fish pond

It is possible to keep an extensive combination of fish in your pond. Because there are so many options it can be difficult to choose. For this reason I have listed a number of options for you below:

Koi carps

A koi carp is considered a beautiful fish by many people because of its colors. Because the koi has a pleasant personality and gets along well with other pond fish it is a good choice to go for a carp in the pond. Ponds with koi fish in them are called koi ponds.

Catfish

A catfish, also called an Ancistrus are tolerant fish to keep in the pond or aquarium. The fish is an active bottom dweller as it swims around a lot. Good to know is that this fish can be territorial, therefore it is recommended to take only 1 of them.

Gold zipper

A goldfish is a small fish that can reproduce quickly and easily. This fish lives mainly on the bottom of the pond because that is where it looks for its food. The fish occupies little surface area making it ideal to keep in large numbers in the pond.

Sturgeon

A sturgeon is by nature a strong fish so he will not easily contract diseases. Because a sturgeon can grow significantly in size after a number of years, it is important that there is sufficient space in the pond, keep a water body of at least 1,000 liters with a depth of at least 1.20 deep. Because the sturgeon needs enough room to swim, it is important to add pond plants to your pond that will not get in the sturgeon's way such as marsh plants, water lilies and other floating plants.

Depth Fish pond

The ideal depth of a pond for fish varies depending on the type of fish you want to keep. However, it is generally recommended to have a pond that is at least 80 centimeters deep. This provides enough space and stability for several types of fish, including goldfish and koi. For larger and more exotic fish species, such as koi, a depth of 1.5 to 2 meters or even deeper may be necessary, especially in areas with harsh winters. A deeper pond provides the fish with needed protection from extreme temperatures and predators.
