What is a skimmer?
A pond skimmer is a device used to remove dirt and organic material from the surface of the water in the pond. The device is usually installed on the side of the pond and has an opening located just below the water line. The dirt and organic material on the surface of the water is sucked into the skimmer by the flow of water and collected in a basket or filter. Using a skimmer prevents the debris from sinking to the bottom of the pond, keeping the water clearer and making the pond easier to maintain. Skimmers are often used in conjunction with other equipment, such as filters and pumps, to improve pond water quality.
How does a floating skimmer work?
A floating skimmer works through a floating housing equipped with a built-in pond plant filter. The device is placed in the pond and floats on the surface of the water. As it floats, an attached pump draws in water and debris through an inlet opening, which is collected by the filter and stored in a catch basin or bag. The skimmer is equipped with a float and a sump, which are held in place by a cable or rope attached to the pond bank. The water in the pond is drawn in through the inlet opening of the skimmer by means of the pump. The water passes through the filter in the housing of the skimmer, where the debris is collected. The filtered water then flows back into the pond through an outlet opening at the bottom of the skimmer.
Disadvantages of Skimmers
Skimmers are not suitable for all types of ponds, because they can interfere with the natural flow of the water and disturb the ecological balance of the pond. In addition, maintenance is required for a skimmer to function properly, such as regular cleaning of the filter and emptying the sump. Skimmers can also be a significant investment, and their installation may involve additional costs, such as the purchase of a pump and any piping. Finally, skimmers can remove beneficial bacteria from the system, requiring extra attention to maintain water quality and water values up to standard.
How do I make a natural pond filter?
With the right pond substrate and the right combination of aquatic plants and pond bacteria, a natural filter is created in the pond. The pond water comes into balance and no more skimmers, pumps and / or filters are needed. With our tips and ready-made pond packages, realizing a pond that is completely balanced is not difficult, as long as the pond is set up correctly.
Skimmers are unnecessary when the pond is set up correctly
Skimmers bring disadvantages and are not good for the environment, for this reason choose a natural pond. When your natural pond is properly designed and constructed you will not need a skimmer or other equipment. - Simon

How does substrate work as a filter?
The substrate is porous so that when water flows past it, dirt particles get trapped in the pores. Thus, the substrate acts as a filter medium that removes these particles from the water. The smaller the pores of the substrate, the finer the particles it holds.
Certain types of bacteria attach themselves to the substrate and break down organic matter and ammonia into less harmful substances.
Frequently asked questions about Skimmers
When you use a skimmer for a pool, you need it to filter floating debris from the water. When you build a natural swimming pond, this function is taken over by the plants and substrate, so you don't need a skimmer.
Our recommendation is NOT a skimmer for the pond. Skimmers can upset the balance of the pond and a skimmer in a pond can be considered unsightly because it is a large object visible on the surface of the water. This can detract from the natural appearance of the pond.

Simon's vision is to let nature do its work in your pond. No need to buy all kinds of measuring equipment and water improvers. If the fish are swimming nicely and the plants are growing well, then the water in the pond is of good quality. With a good planting plan and the right approach, you can save a lot of money and maintenance, and ensure a clear, biologically balanced pond that becomes more beautiful every year.
