What is a Pond Skimmer?
A pond skimmers will keep your water clear by removing large particles such as leaves and twigs from the surface water. Its weir doors rise and fall as required, collecting floating waste into a basket which can be emptied easily.

Manufacturers understand that each pond is unique and offer different skimmers with different GPH flow rate to match your pump. To maximize the effectiveness of your unit, choose a model that has a matching flow rate.
Debris removal
The main purpose of the pond skimmer is to collect large floating organic debris like leaves, grass clippings or other organic matter. This helps to keep the pond’s water cleaner and healthier by preventing algae growth.
Even the most clean pond can accumulate a layer due to oil from fish, plant waste, food, dissolved organics, and more. This causes the water to look dirty while inhibiting its natural bacterial cleansing. To eliminate this buildup, a skimmer will be needed to keep the water healthy and clear.
In most skimmers, the leaf net is mounted in front of the unit to capture organic material. A filter pad is placed behind this frame and used to collect any debris that may have made it past. This pre-filtration prevents an overflow of debris into the system which could clog up its filters, reducing both maintenance costs and frequency.
Some skimmers use a floating device that moves with the level of water to maximize their efficiency and collect debris from all corners of the pond. Other designs utilize a weir to restrict flow into the skimmer to prevent overflow. Although more complex, they tend to be the most efficient.
When installing a pond skimmer, it is important to place it close to the opening so that you can easily empty debris and sludge if necessary. Some skimmers have the option to direct their contents to drains that are used for plant beds, reducing waste disposal fees.
Aeration
Skimmers are an essential part of any water filtration system. They remove debris that cannot sink and floats at the surface. They also support the health of your pond. Skimmers can remove leaves, twigs and pollen as well as plant debris. This helps maintain a healthy ecosystem by keeping it free of toxic substances.
A reliable skimmer has a weir to control the amount of water that enters, and also a basket or a net for catching smaller debris at the surface of your pond. Many skimmers come with secondary filters or brushes that collect particles at the surface of your pond.
Make sure the skimmer you choose is the correct size for your pond. The larger the skimmer, the more debris it can hold. This means that smaller models will need less maintenance. Consider where you would like the skimmer to be installed. For best results, install it opposite any waterfalls or returns of water.

It is the most efficient type of skimmer because it does not require electricity. These types are great for ponds that have a lot of foliage during autumn or small outdoor ponds. To ensure a successful pond skimmers system, submerge the base and tilt it before turning on this type. Check regularly your net to make sure it is free of debris. Empty the basket as needed.
Filtration
Pond skimmers form the foundation of any effective filtration systems for aquatic ecosystems. They collect floating debris, before it sinks and decomposes. They are simple to use and feature a weir, which is an opening that sits on the surface of water. As your pump draws water through the weir, floating debris is trapped in its mechanical filtration medium – typically a mesh or rigid basket that’s designed to capture leaves or larger objects. You can combine them with biological filters such as Matala mat filter to get even better cleaning and filtering results.
Skimmers may be installed on the ground or at the edge of a pool. However, some models are designed to float above the water. This option is generally not recommended because the wind movement and the movement in the pond can make it unfeasible. The best pond-skimmers are made with aesthetics in consideration. Many have rock-like lids, or different colors that will blend into the surroundings.
The pond skimmers also provide a valuable service in that they prevent ammonia from building up in the water. Ammonia is produced when organic material starts decomposing, and can be toxic to fish. Skimmers can stop this ammonia buildup in its tracks by removing floating debris and preventing it from sinking to the bottom.
Pond skimmers are not meant to be standalone filters. Instead, they must be used in conjunction with other biological and chemical filters like matala filter pads and pumps. This will keep the water healthy and clean. If you do not have these systems, your pond can suffer from algae blooms, harmful levels of ammonia, and other issues that could endanger aquatic life and fish. By pairing your skimmer and these other components together, your backyard pond is sure to remain healthy and beautiful all year round!
Maintenance
A pond skimmer is designed to keep surfaces free of debris to maintain healthy ecosystems.
If organic debris is allowed to accumulate on the floor of a pond, it will eventually sink and decompose. This produces toxic chemicals that can harm aquatic life. Submersible pumps may also become clogged if floating debris reaches them. To avoid any problems, it’s best to eliminate the debris before it can cause them. This is why a professional pond skimmer is an important component in any healthy system.
These skimmers can be very effective, but they may need additional maintenance. They work best on smaller ponds.
A pond skimmer that is external to the pond can also be a viable option. It sits outside and is connected with its pump and plumbing. This model offers better performance and maintenance than built-in models, as well as a debris collection basket.
It is possible that the unconsumed fish food could exceed the capacity of the ecosystem and lead to unwanted algae growth or extreme plant development. Skimmers prevent this from happening by catching uneaten pellets, before they float up to the surface and fuel extreme plant growth or algae blooms.

Professional pond skimmers come with many features to protect the filtration system, and to reduce cleaning costs. They include rigid nets or baskets that have rigid walls. These are designed to catch large pieces of debris prior to entering them into the filtration system. The floating weir door, which rises and falls with the water level, increases efficiency by pulling out debris from every corner of the pond. It also has corrosion-resistant metal hardware that is resistant to environmental conditions. While such features are more expensive than plastic baskets, they can save you money in the long-term by preventing costly cleanups and protecting your investment.
