Major pond maintenance: How to minimize pond maintenance

Major pond maintenance is done once every five years, the pond is then drained and cleaned which minimizes pond maintenance.

The importance of great pond maintenance

Major pond maintenance is important to keep pond water and the aquatic plants and aquatic animals in the pond healthy. If too much mud and waste accumulates at the bottom of the pond or if pond plants overgrow the pond, this can lead to poor water quality due to lack of oxygen causing algae blooms and eventually fish die. Major maintenance, where the pond is completely emptied and cleaned, along with a properly landscaped pond, helps to solve these problems and get the pond back into balance.

Why pond maintenance alone is not enough for a healthy pond

Major pond maintenance is necessary because seasonal maintenance is not always sufficient to ensure the long-term health of the pond. Maintenance such as leaf removal and water replenishment is important, but if too much mud and waste accumulates at the bottom of the pond, it can lead to poor water values and problems for fish and other aquatic animals. In addition, aquatic plants may overgrow the pond, necessitating intervention. Also, pond liner can become porous after several years and must be replaced. Major maintenance, which involves completely emptying and cleaning the pond, can help solve these problems and restore the pond to a healthy, clear condition. Seasonal maintenance is thus a good basis, but major maintenance is necessary to keep the pond in top condition.

Reasons for major pond maintenance

Improving water quality

By completely emptying and cleaning the pond, accumulated mud, waste products and excess nutrients can be removed. If this is not done once every five years, the pond water will suffer from excessive algae formation turn green which will turn the pond and any pond fish and other pond animals will not benefit.

(EPDM) pond liner

If you pond liner have PVC and it has become porous, major maintenance may be necessary. In fact, after five to 10 years, PVC liner can become porous and the pond will leak. The only solution then is to install new liner. Fortunately, rubber liner has a much longer lifespan than PVC liner, so you won't run into problems with it.

Overgrown aquatic plants

When aquatic plants overgrow the pond, simply pruning back is often no longer an option. In that case, you must take a more rigorous approach and empty the pond completely to remove the aquatic plants, especially their stubborn root systems, from the pond. It seems like a big job, but the result is a pond that is healthy and balanced again.

Step 1: Emptying the pond

Draining a pond is a big job best done in the fall or early spring. To pump out the pond, you need draining equipment, such as a dirty water pump and a hose that you hang in the drain. Start by pumping the pond half empty before you begin removing your fish and aquatic plants. Be sure to keep them in the original pond water in a separate container so they are safe while cleaning the pond.

Step 2: Removing the mud layer

Once the pond is drained, it is time to carefully remove the mud layer from the bottom, without damaging the liner. Also remove as much as possible of the roots of aquatic plants in the mud. aquatic plants or cuttings you want to keep can be planted back into planting baskets. A drained pond provides an opportunity to check the pond liner . Consider replacing the entire liner, especially with PVC liner, now that the pond is empty anyway.

Step 3: Setting up the pond

Now that the pond is completely empty and clean, it's time to redecorate it. Choose the right aquatic plants you want to place in the pond and add any old plants that are still intact. Be sure to choose aquatic plants with different functions so they can optimally filter the pond water and keep it healthy. Consider not only oxygen plants, but also add marsh plants, water lilies, floating plants and other aquatic plants to keep the pond balanced.

Step 4: Filling the pond with water

The water level in the pond will change over time. In hot summers with lots of sunshine, water evaporates, so the water level drops. It is necessary to refill your pond with water as soon as this happens. This will ensure that the pond liner is not exposed to sun and other weather conditions and will prevent leaks from occurring as quickly. A good water level is also essential for your pond plants. Don't refill your pond completely at once, but spread smaller amounts of water over several days. This will best maintain the biological balance in your pond. You can use either groundwater or tap water.

Step 5: Starting up the pond

Start up the pond by adding pond bacteria to the water. Pond bacteria provide a good start because although they are not visible to the naked eye, Pond bacteria play a crucial role in maintaining a healthy pond. These microorganisms are vital to the biological balance of any pond and ensure that your pond stays clean and clear all year round.

The best time for major pond maintenance

The best time for major pond maintenance is usually in the fall or early spring, when water temperatures are still relatively low and there is less chance of harmful algae blooms.

Removing the silt layer from the soil

To remove the mud layer, it is recommended to pump out the pond. Be sure to do this carefully without using sharp objects so that the pond liner is not damaged. Once the layer is removed, you can rearrange the pond and fill it with water.
