You can choose from a wide range of pond filters and pumps, all designed to perform specific tasks. The majority of ponds use mechanical filtration, also known as physical sifting, to keep the water clear. This is done by filtering out leaves and other debris.

Many pond pumps come with step-down hose connectors that allow you to connect tubing in different sizes. Choose an adapter that has step-down capabilities when choosing the tubing size to match your recommended filter intake size and maximum flow rate.
Pond Pumps
Pumps are essential to a healthy water garden or pond. They help oxygenate the water and create a beautiful pond. The right pump size will create an ecosystem that is conducive to fish and plants flourishing. A pump too small may not be able to power the waterfalls or create the desired height of the fountain. While a large pump can create elaborate fountains, but may lack the circulation power necessary to rotate the water body in the pond 2-4 times per hour.
Filters are required for most pond pumps to work optimally. A good filter will catch and break down waste material before it enters into the pump or plants. Prefilters can be installed on the pump intake or around it to catch large debris. Pressurized filters are another great option. They use pressure to filter the water and return it directly into their ponds.
All pond pumps must be serviced regularly to remove any residue, especially if they are used for fish ponds. Citric acid can help dissolve the buildup, and prevent internal parts of the pump from being damaged or blocked by unattended feed deposits at its bottom.
Brush the pump cage to remove debris such as leaves, twigs, and weeds which could clog up your pump. Laguna PowerClear Multi All in One, which combines a filter, UV clarifier and pump into one unit, is a great option for small pond owners. This unit keeps their pond healthy and clear.
It is best to choose models that run on low voltage when purchasing a filter and pump for your pond. This will make the installation easier and safer, without needing electricians or extension cords to be run from nearby outlets. It allows owners of ponds to use an extension cord rather than running wires from an outlet directly into their water feature.
Filters
Pond filters are an essential part of any garden pond's ecosystem. They ensure that water flows freely and life can grow within the confines. Pond filters are used to "handle solids", removing physical debris such as leaves, twigs, and algae that can enter through strong winds, or collect on the bottom. Physical or mechanical filters are also known as mechanical or physical filters.

They consist of canister and skimmer filters that skim, trap, or hold solid debris. Sometimes they are combined with UVC clarifyers. It is recommended that when cleaning these filters, the media be rinsed in pond or septic water rather than tap water to ensure high levels of beneficial bacteria and maximum filtration. It is also recommended to stagger the cleaning of filters in order to maximize filtration efficiency.
Microbes on the bottom will also break down any toxins that are produced by dead plants or fish, and balance your ecosystem. This type of filtration will help protect your pump by limiting the build-up of sludge and maintain a healthy ecosystem.
Smartpond's Biological Pond filter uses two filters pads and bio-balls that work in conjunction with the pump to circulate water throughout your pond. It is our most popular product, ensuring proper circulation of pond-life!
The built-in system of pressure ensures that the flow rate through the pump is constant. This prevents overworked pumps from causing damage. Ideal for ponds of up to 850 gallon.
It is important to consider several factors when selecting a pond filtration system. These include the height of the pump head (the point at which water returns), power consumption, and noise level. Choose an energy-efficient model that can provide enough wattage all year round without overheating.
Pond Skimmers
Skimmers are a must-have for any backyard pond. This machine, which is placed along the edge of the pond, continuously sweeps water's surface in search for leaves and sticks that might float.
Skimmers are essential for protecting pond pumps, as they prevent debris from entering and clogging them. This would otherwise wear out or shut down the pump. Skimmers can also reduce ammonia levels as organic matter such as grass, leaves, sticks and fish waste decomposes, creating an ammonia rich environment toxic to aquatic life.
Skimmers can help by trapping debris and preventing it from sinking into your pond. This will keep the ammonia level down. You can also combine skimmers with UV clarifiers in order to reduce ammonia levels further.
A bog filter can be used to maintain balance in a pond that does not contain fish or other wildlife. To achieve this, you will need to cover two-thirds with plants that cover two-thirds the area. You can also use naturally occurring bacteria which digest visible toxins from fish and organic material.
A rock bog filter that is effective can be constructed on site using full-sized (8x8x16") cinderblocks and 4x8x16" cinderblocks mortared together. This will form a 12 inch deep pit, plus 4-6 inches above the filter for the optional waterfall and pond liner. This allows the piping to be run down from the retaining wall into the bog without disturbing plant beds.
Aerators
Aerators circulate and stir water, creating a healthier environment for fish, plants, and wildlife in your pond. Aerators also help reduce ammonia and prevent algae growth. They are available in different sizes to suit both large and small ponds.
Calculate the volume of your pond by measuring its length, width, and depth. This figure will help you choose a pump that has a flow rate suitable for your pond volume. For example, a waterfall might require a higher head height than a standard pond pump! Look for a pump with adjustable flow rates to tailor the amount of water that is pumped out by your pond pump.
It is important to keep in mind that a filter system's filter contains many beneficial bacteria that work to reduce levels of ammonia, nitrite and other toxins that can harm aquatic life. The filter can also become a home to slimy gunk or debris that could cause pumps to block if low density filter media are not used.

Box and pressurised pond filters are the two main types. Each filter offers a unique benefit, while both provide high-level filtration. Box filters (also known as non-pressurised filter) are best for creating rustic styles in ponds, especially when combined waterfalls. These types can be placed at the bottom of or above the water level.
The most popular choice for backyard fish ponds is the pressurised pond filter. These filters are often buried or submerged below the surface. These filters can process more water than box-style filters, and are easier to maintain. They also connect easily to electrical sources.
