Buying a pond filter? Don't do it!

Think every pond needs a filter? Think again! A well-designed pond with plants will save you energy as well as worry.

What is a pond filter?

A pond filter is a device used to clean and purify the water in a pond. It is designed to filter out unwanted substances such as food debris, pond fish droppings, leaves, algae and other particles from the water, keeping the water clear and healthy.

Plants can do this too!

If you set up your pond correctly, a pond filter is unnecessary. A pond that is equipped with a layer of porous substrate on the bottom, planted with various types of aquatic plants and where twice a year a bottle of pond bacteria Bacta Clear is added, remains clear and healthy in a completely natural way without you having to maintain it. Together, these elements create a self-cleaning ecosystem, eliminating the need for the use of a mechanical filter.

My vision is to let nature do its work in your pond. You don't need to buy all kinds of measuring equipment and water improvers. If the fish are swimming nicely and the plants are growing well, you know the water is of good quality.

Pond filter vs plant filter

A pond filter becomes obsolete in a pond that is properly decorated with oxygen plants, among other things. These plants purify and aerate the water, produce oxygen, absorb nutrients, and prevent algae growth. As a result, they improve water quality and biological balance in the pond. I sometimes speak to pond owners who complain about high energy costs from using oversized pumps, filters, UV lamps, air pumps and water bottom vacuums. Below I show you a natural and sustainable alternative.

Tip from Simon: More plants in your pond is always better.

Too few plants increases the risk of algae and plant death. If necessary, choose additional plants you like in addition to the package.

What should be in a pond filter?

Several components are essential in a pond filter. Filter foam and filter wads are excellent for mechanical filtration, as the strong nylon fibers remove coarse dirt from pond water. For biological filtration, it is particularly useful to use filter lava because it is ideal for bacterial breakdown of invisible dirt and pollutants.

What is the best filter for the pond?

For a beautiful, clear and healthy pond environment where aquatic plants can grow abundantly and fish and other pond animals feel at home and which also promotes biodiversity, it is important to design the pond in a natural way. Pumps and filters do not belong here, aquatic plants do, therefore it is important to plant your pond according to our pond planting plan. One option is to plant all kinds of water plants loose in the pond to create a natural filter, but you can also choose to build a plant filter, these are both natural options. For constructing a plant filter, we have all kinds of cleverly composed plant filter plant packages.

How big should the pond's filter be?

The size of the filter for a pond depends on several factors, including the presence of fish. In general, in a pond without fish, a filter with a capacity equal to the volume of the pond is sufficient. So for example, in a 10,000 gallon pond with no fish, a filter with a capacity of 10,000 gallons would suffice. However, if you plan to keep fish in the pond, then it is recommended to count on a filter with double the capacity. In this case, in a 10,000-liter pond with fish, you should consider a filter with a 20,000-liter capacity. This is because fish affect water quality by producing waste products, so a larger filtration capacity is needed to keep the water clear and healthy.



What types of pond filters exist?

You have created a pond in the garden and want it to stay clear and healthy. There are several types of pond filters that can be used to do this, including options that are not harmful to the environment and promote biodiversity. Below I list a few of them:

Mechanical filters

First, you have the pond filter as many know it, which is the "Organic Pond Filter. These filters work by removing particles from the water through a fine mesh filter mat or filter brushes. The water is pumped through the filter and the larger particles are left behind in the filter mat or on the filter brushes. Disadvantages of this filter are that it is expensive to purchase, it looks unnatural in the pond, it causes higher energy costs and the filter requires maintenance to remain functional in the pond. Other pond filters that are mechanical and perform a similar function in the pond are: 'the UV filter' and 'the Skimmer'. The UV filter uses ultraviolet light to kill harmful bacteria, viruses and algae. Water is pumped through the UV lamp and the UV light kills the harmful organisms. Skimmers keep the water surface clean by removing leaves, branches and other floating debris from the pond. They have a basket in which the debris is collected.

Biological filters

What people sometimes do not know is that a pond can also be filtered completely naturally by planting sufficient and different types of aquatic plants in the pond. The plants that are indispensable in every pond are: 'Oxygen plants', 'Sumpfpflanzen' and 'water lilies'. These pond plants each have an important function in maintaining a healthy and balanced pond. Oxygen plants, as the name suggests, oxygen plants produce oxygen through photosynthesis. During photosynthesis, plants absorb carbon dioxide and water and produce oxygen as a byproduct. Oxygen plants are therefore essential for maintaining a healthy and balanced pond ecosystem because they provide a continuous supply of oxygen for fish and other pond animals.

How often should a pond filter be cleaned?

It is wise to thoroughly clean your pond filter once or twice a year. Otherwise, the filter is likely to become clogged with algae and other debris.

How does a low-pass filter work?

A low-pass filter allows low-frequency signals to pass through and attenuates or blocks high-frequency signals. This type of filter is often used to reduce unwanted high-frequency noise or to make a signal more uniform by reducing high-frequency components.

How does a flow-through filter work?

A flow-through filter is placed at the edge of the pond, above the water. The pump in the pond pumps the water up to this filter. After the water is cleaned by the filter, it flows back into the pond. It is important that the outlet of the filter is higher than the edge of the pond.

Do you need a pond filter and pond pump?

For a beautiful, clear and healthy pond environment where aquatic plants thrive and fish and other pond animals feel at home, while at the same time promoting biodiversity, it is essential to design the pond in a natural way. In this case, pumps and filters do not fit the bill, but aquatic plants do. This is why it is essential to plant your pond according to our Step-by-Step Plan. Several options are available, such as planting various types of aquatic plants separately in the pond to create natural filtration. Another option is to construct a plant filter, both of which are natural approaches. If you choose to construct a plant filter, we offer several conveniently assembled plant kits to help you do so.
